What Bearing Should You Use for Mining Vibrating Screens, Rolling Mills and Fans? A Complete Guide to Spherical Roller Bearings

The self-aligning roller bearing is a double-row radial rolling bearing with drum-shaped (spherical) rolling elements. The outer ring has a shared spherical raceway, and the inner ring has two raceways inclined at a certain angle to the bearing axis. This ingenious design gives it automatic self-aligning capability, making it less susceptible to errors or shaft bending caused by the angle between the shaft and the bearing housing. It is suitable for installation errors or shaft deflection causing angular errors. In addition to withstanding radial loads, this bearing can also withstand bidirectional axial loads, offering high radial load capacity. It is especially suitable for operation under heavy or vibrational loads, but cannot withstand pure axial loads. The center of curvature of the outer raceway surface matches the center of the bearing. When the shaft or housing deflects, it can be automatically adjusted without increasing bearing load. When the shaft is bent or tilted by force, causing the centerline of the inner ring to tilt relative to the outer centerline by no more than 1°–2.5°, the bearing can still operate. Spherical roller bearings have two inner bores in cylindrical and conical shapes. The tapered bore of the conical type has taper diameters of 1:12 and 1:30. Paired with a setting sleeve or retraction sleeve, the tapered inner bore bearing can be conveniently and quickly mounted onto the plain shaft or stepped shaft. To enhance the lubrication performance of the bearing, annular oil grooves and three evenly distributed oil holes are machined on the bearing outer ring, with the suffix W33 indicating this design. Common structures include the 20000CC type (inner ring without flange, with movable retaining ring, stamping cage), 20000CCK type (tapered hole), 20000CC/W33 type (with oil groove oil hole), 20000CCK/W33 type (tapered hole with oil groove oil hole), and the 20000CCK+H type mounted on the setting sleeve, among others. Priority should be given to the optimized 20000CC and 20000TN models with optimized structures. Why choose self-aligning roller bearings? First, the automatic self-aligning performance is excellent, compensating for angular deviations of up to 1°–2.5° between the shaft and the seat hole, suitable for conditions where centering is difficult due to foundation settlement, long shaft warping, or insufficient installation accuracy; Second, large load capacity: the double-row drum-shaped rollers are in linear contact with the raceway, capable of withstanding extremely heavy radial and bidirectional axial loads, especially suitable for heavy loads and impact loads; Third, it combines self-aligning and impact load adaptability, effectively absorbs vibration, protects the transmission system, and performs exceptionally under harsh conditions such as mining vibrating screens and rolling mills; fourth, installation is flexible, conical bore bearings can be mounted on cylindrical shafts using either a set sleeve or a withdrawal sleeve, allowing installation at any position on a smooth shaft and adjustment of radial clearance; fifth, lubrication and maintenance are convenient, the W33 type outer ring features an annular oil groove and three evenly distributed oil holes, making it easy to replenish grease during operation and extend service life. Self-aligning roller bearings are mainly used in: vibrating screens, crushers, and hoists in the mining industry, with vibrating screen bearings widely used in mining vibrating machinery, making them one of the most critical components under very harsh working conditions; rolling mill gearboxes and rollers in the metallurgical industry, where 32370 self-aligning roller bearings are suitable for low and medium-speed applications that carry heavy and impact loads; main shaft support positions in fan drive systems, especially for large fans with long shafts or potential misalignment due to foundation settlement; input and output shaft supports of reduction devices; vertical mills and rotary kilns in cement machinery; paper machinery, petroleum machinery, and railway vehicle axles; as well as crushers, vibrating screens, printing machinery, woodworking machinery, and various industrial machinery. Those who need self-aligning roller bearings include: mining equipment manufacturers and operation & maintenance teams, metallurgical rolling mill and gearbox manufacturers, fan and reducer manufacturers, cement and paper equipment manufacturers, vibrating screen equipment manufacturers, industrial equipment distributors and bearing stockists, maintenance and replacement procurement teams, and overseas EPC contractors. When should self-aligning roller bearings be selected or replaced? When the equipment has installation errors or shaft deflection and alignment accuracy is difficult to guarantee, requiring self-aligning capability; in heavy-duty impact conditions such as mining vibrating screens and crushers, requiring high radial load capacity and impact resistance; for fan main shaft support where long shafts or foundation settlement may cause misalignment; when rolling mill gearboxes and rollers need to bear heavy and impact loads; when old bearings experience early fatigue spalling of raceways due to poor alignment and need to be replaced with self-aligning bearings; when equipment needs to simultaneously bear radial and bidirectional axial combined loads; or when export projects require bearings interchangeable with GB/T 288 or ISO standards. How to select self-aligning roller bearings? Step 1: Determine the type of load. Spherical roller bearings primarily bear radial loads and can also support bidirectional axial loads, but they cannot support pure axial loads. If there is a large pure axial load, a thrust bearing should be used in conjunction. Step 2: Determine the structural type. Cylindrical bore is used for standard installation, while tapered bore (K taper 1:12, K30 taper 1:30) is installed on a cylindrical shaft with a mounting sleeve or withdrawal sleeve, making it easy to adjust clearance and assemble/disassemble. Step 3: Determine the size series. Choose the series 21300/22200/22300/23000/23100/24000/24100 according to the shaft diameter, prioritizing 20000CC type or 20000TN type optimized design products. Step 4: Select the clearance. Cylindrical bore bearings have standard clearance CN, while tapered bore bearings typically have radial clearance C3 (greater than the standard group) to accommodate thermal expansion and interference fit. Step 5: Determine the accuracy level. P0 is suitable for general machinery, P6 or P5 for vibrating screens and precision equipment. For vibrating load conditions, consider the T41A tolerance class with a narrower clearance, specifically for vibrating screens. Step 6: Confirm the cage. The standard is a stamped steel plate cage. For heavy-duty conditions, a machined brass solid cage (M suffix) can be selected. For vibrating conditions, a stamped steel plate cage (JPA suffix) is suitable. Step 7: Confirm the installation fit. When a tapered bore bearing is installed with a mounting sleeve, measure the reduction in radial clearance, and recheck the clearance at six points at the bottom using a feeler gauge. Step 8: Confirm the lubrication method. W33 type outer ring has lubrication grooves and three oil holes, convenient for adding grease during operation. Sealed types can be 2RSR (nitrile rubber) or 2VSR (fluorine rubber).

Key points for installation check: Self-aligning roller bearings are double-row non-separable bearings with inner rings available in either cylindrical or tapered bore. Bearings with a cylindrical bore are installed with conventional interference fit. Tapered bore bearings (taper 1:12 or 1:30) can be installed directly on a tapered shaft or on a cylindrical shaft using an adapter sleeve or withdrawal sleeve. Large self-aligning roller bearings are mostly installed with hydraulic pressing. An oil hole is set in the adapter sleeve, and high-pressure oil is fed into the fitting surface. As the bearing radially expands, a sleeve is inserted axially using adjustment bolts. During installation, the reduction in radial clearance must be checked using a feeler gauge. For inner diameters ≤120mm, measure the uninstalled clearance at the top (12 o'clock position) and re-measure at the bottom (6 o'clock position) after pressing into place with the tapered surface. After installation, ensure the outer ring can align flexibly, and the clearance should not be too small. Cages used include stamped steel cages, molded polyamide cages, and machined copper alloy cages. The bearing outer ring is machined with an annular oil groove and three evenly spaced oil holes (W33 suffix) to facilitate lubrication replenishment during operation.

Note: Spherical roller bearings cannot withstand pure axial loads. If there is a large pure axial load, a thrust bearing should be used in conjunction. When installing bearings with tapered bore, it is necessary to accurately measure the reduction in clearance to ensure that the self-aligning performance is not affected. For vibrating conditions, it is recommended to use T41A tolerance class with a narrower vibration screen-specific type. For high-temperature conditions, it is recommended to choose 2VSR fluororubber seals, suitable for temperatures up to 200°C–250°C.

Selection Considerations (compared with tapered roller bearings and cylindrical roller bearings): The core difference between spherical roller bearings and tapered roller bearings or cylindrical roller bearings lies inself-aligning ability and load type. The core advantage of spherical roller bearings is their double-row rollers and spherical outer ring raceway design, providing excellent self-aligning performance, usually able to automatically compensate for angular deviations of 1°–2.5° between the shaft and housing. They are suitable for installations with low precision or prone to deformation. When dominated by radial loads or with impact loads, spherical roller bearings are preferred. Additionally, their maximum speed is generally higher, making them more suitable for high-speed operation of fan shafts. Tapered roller bearings do not have self-aligning ability, but can withstand larger combined radial and axial loads, and high rigidity support can be achieved by adjusting the clearance, making them suitable for components requiring precise axial positioning and high rigidity, such as the input/output ends of gearboxes or speed reducers. Cylindrical roller bearings mainly bear radial loads, have high radial load capacity, and high limiting speeds. NU/N types cannot withstand axial loads, while NJ/NUP types can withstand unidirectional/bidirectional axial loads, suitable for heavily loaded radial conditions with certain requirements for maximum speed. In selection: for difficult alignment or shaft deflection conditions, spherical roller bearings are preferred; for precise axial positioning and high rigidity, tapered roller bearings are preferred; for heavy pure radial loads with good alignment, cylindrical roller bearings are preferred.

## Technical FAQ

1. What is a spherical roller bearing?

A spherical roller bearing is a double-row radial bearing with barrel-shaped (spherical) rollers. The outer ring has a single shared spherical raceway, and the inner ring has two raceways inclined at a certain angle relative to the bearing axis. It has self-aligning performance, mainly bears radial loads, and can also withstand bidirectional axial loads.

2. How to read spherical roller bearing model numbers?

The model number consists of the size series + inner diameter code + structural suffix. For example, in 22220CC/W33: 22 is the size series (light and wide), 20 is the inner diameter code (20×5=100mm), CC is an optimized design stamped cage, and W33 indicates the outer ring has an oil groove and three oil holes. K indicates a tapered bore (taper 1:12), K30 indicates a tapered bore (taper 1:30), TN indicates a nylon cage, and M indicates a brass solid cage.

3. What are the main series of spherical roller bearings?

Series include 21300, 22200, 22300, 23000, 23100, 23200, 23900, 24000, 24100, etc. 21300 is an extra light narrow series, 22200 is a light wide series, 22300 is a medium wide series, 23000 is an extra light narrow series, and 24000 is an extra light wide series. Preferably, products of the 20000CC and 20000TN types with optimized design should be chosen.

4. What is the alignment angle of spherical roller bearings?

They can automatically compensate for angular deviations of 1°–2.5° between the shaft and housing bore, and the bearing will still function if the inner ring center line and outer ring center line tilt relative to each other within 1°–2.5°.

5. Can spherical roller bearings withstand axial loads?

They can withstand bi-directional axial loads but cannot withstand pure axial loads. If there is a significant pure axial load, a thrust bearing must be used together.

6. What do the spherical roller bearing model suffixes CC, CA, TN, M, W33, K, and K30 represent?

CC indicates an inner ring without flanges with a movable center ring and optimized stamped cage; CA indicates an inner ring with flanges with a movable center ring and machined brass cage; TN indicates a glass-fiber reinforced polyamide 66 cage; M indicates a machined solid brass cage; W33 indicates the outer ring has a lubrication groove and three oil holes; K indicates a tapered bore (taper 1:12); K30 indicates a tapered bore (taper 1:30).

7. What is the material of spherical roller bearings?

The standard material is GCr15 high carbon chromium bearing steel, with optional GCr15SiMn and carburizing steel. The standard cage material is stamped steel (CC type), with optional machined solid brass cage (M suffix), glass-fiber reinforced polyamide 66 cage (TN suffix), and stamped steel cage for vibration occasions (JPA suffix).

8. What is the limiting speed of spherical roller bearings?

Taking 22220CC/W33 as an example, the limiting speed with grease lubrication is 2200 r/min, and with oil lubrication is 2600 r/min. For 22320, the limiting speed with grease lubrication is about 3000 r/min. For large models such as 23148K, the limiting speed with grease lubrication is 670 r/min, and with oil lubrication is 850 r/min.

9. What are the accuracy classes of spherical roller bearings?

The standard is P0 (normal series), optional P6 and P5 can be chosen. For ordinary machinery, P0 is sufficient; for vibrating screens and precision equipment, P6 or P5 is recommended.

10. How to choose the clearance of spherical roller bearings?

Cylindrical bore bearings have a standard clearance of CN (normal series). Tapered bore bearings usually have a radial clearance of C3 (greater than the normal series) to accommodate thermal expansion and interference fits. For heavy-duty impact conditions, C4 can be selected. For specialized vibrating screens, the T41A tolerance band narrower variant can be chosen.

11. Can spherical roller bearings be used in mining vibrating screens?

Yes, they are the core bearing type for mining vibrating screens. Bearings in vibrating screens are mostly used in mining vibrating machinery where working conditions are very harsh. Considering the load characteristics caused by eccentric shafts of vibrating screens, it is recommended to use spherical roller bearings with high load capacity and good impact resistance, equipped with a brass cage and C3 clearance.

12. Can spherical roller bearings be used in rolling mills?

Yes, the 32370 spherical roller bearing is suitable for occasions that require bearing heavy loads and impact loads at low and medium speeds, and it is widely used in rolling mill gearboxes and rolling mill rolls.

13. Can spherical roller bearings be used in fans?

Yes, due to their excellent self-aligning capability and impact load adaptability, they are often used in the main shaft support positions of fans, especially for long shafts or large fans that may experience misalignment due to foundation settlement. They can effectively absorb vibrations and protect the transmission system.

14. How to choose the installation fit for spherical roller bearings?

Cylindrical bore bearings use conventional interference fits; the shaft should be k6/m6 and the housing H7. Tapered bore bearings are installed using a solid or withdrawal sleeve; the shaft should be h9 and the housing H7, and the clearance reduction should be measured during installation. For heavy-duty conditions, the shaft should be n6/p6 and the housing K7.

15. What should be paid attention to when installing tapered bore spherical roller bearings?

During installation, the reduction of the radial clearance must be checked, and a feeler gauge should be used to measure the radial clearance. When the inner diameter is ≤120mm, measure the uninstalled clearance at the top (12 o'clock position). After pressing into position using the tapered surface, re-measure the clearance at the bottom (6 o'clock position). Large spherical roller bearings are mostly installed using hydraulic pressure, employing a hydraulic nut to slide the bearing into place. After installation, ensure that the outer ring can self-align flexibly, and the clearance should not be too small.

16. What does the W33 suffix of a spherical roller bearing mean?

W33 indicates that the bearing's outer ring has an annular oil groove and three evenly spaced oil holes, which facilitate the replenishment of grease during operation, extending service life. This avoids the need to machine a lubrication passage in the bearing seat's inner diameter.

17. Are there sealed spherical roller bearings?

Yes. Standard spherical roller bearings are not sealed. Spherical roller bearings with seals on both sides have the suffix 2RSR (Nitrile rubber double-lip seal on both sides, suitable for medium speeds) or 2VSR (Fluorine rubber double-lip seal on both sides, high temperature resistant up to 200°C–250°C, suitable for high-temperature conditions such as continuous casting machines).

18. What is the difference between spherical roller bearings and tapered roller bearings?

The core advantage of spherical roller bearings is their self-aligning ability (1°–2.5° angular deviation compensation). They mainly bear radial loads, have a higher limiting speed, and are suitable for difficult-to-align conditions with impact loads, such as fan main shafts and vibrating screens in mines. Tapered roller bearings do not have self-aligning ability but can withstand larger combined radial and axial loads. High rigidity support can be achieved by adjusting the clearance, making them suitable for gearboxes and speed reducers that require precise axial positioning.

19. What is the difference between spherical roller bearings and cylindrical roller bearings?

Spherical roller bearings have self-aligning capability and can bear axial loads in both directions. They are suitable for difficult-to-align, heavy-duty, and impact conditions. Cylindrical roller bearings mainly bear radial loads. NU/N types cannot bear axial loads, while NJ/NUP types can bear single or double-direction axial loads. They have higher limiting speeds and are suitable for heavy radial loads with good alignment.

20. Can spherical roller bearings be customized?

Customizable materials (GCr15SiMn/carburizing steel), cages (brass M/nylon TN/vibration-special JPA), accuracy grades (P6/P5), clearances (C2/C3/C4/C5), sealing types (2RSR/2VSR/open), oil grooves and holes (W33), adapter sleeves/withdrawal sleeves matching, high-temperature lubricating grease, etc.

Technical FAQ

When should I use a spherical roller bearing?

Use one when radial load is high or shaft and housing alignment may change. Check speed and axial load limits as well.

What is the role of a CA or CC cage?

Cage design affects guidance, load capacity and operating limits. Select the cage from the manufacturer’s data for the actual duty.
