A spherical roller bearing is a highly engineered rolling-element bearing designed to excel in demanding operating conditions. Its defining feature is its self-aligning capability. It automatically compensates for misalignment between the shaft and housing, caused by mounting errors, shaft deflection, or foundation settling (typically up to 1.5° – 3°). This unique ability makes them the ideal solution for applications involving heavy loads, shock loads, and situations where some flexibility is unavoidable.
Spherical Roller Bearing
| ISO | 23032 MBW33 | |
| GOST | 3003132 H | |
| Bore diameter | d | 160 mm |
| Outside diameter | D | 240 mm |
| Width | B | 60 mm |
| Basic dynamic load rating | C | 300 kN |
| Basic static load rating | C0 | 525 kN |
| Reference speed | 800 r/min | |
| Limiting speed | 600 r/min | |
| Mass bearing | 9.52 kg | |
Structural Design
The bearing consists of four key components:
- Inner Ring:Features two raceways with ribs for roller guidance.
- Outer Ring:Has a concave spherical raceway ground into its bore. The center of curvature of this raceway coincides with the bearing center, enabling the self-alignment.
- Rollers:Barrel-shaped (spherical) rollers, either symmetrical or asymmetrical, roll freely within the outer ring’s spherical path, allowing tilt and rotation.
- Cage:Positions and separates the rollers, minimizing friction and guiding rotation. Cages are typically made of pressed steel or machined brass. The bearing houses two rows of rollers for high load capacity.
Key Characteristics
- Superior Self-Alignment:Tolerates significant shaft misalignment, protecting the bearing from edge stress and premature failure, extending service life.
- Exceptional Load Capacity:The barrel rollers maintain a large contact area with the spherical outer raceway, enabling very high radial load capacity and moderate bidirectional axial load handling.
- Robustness & Shock Resistance:Sturdy construction handles heavy loads, impact loads, and vibrations effectively.
- Optimized Internal Geometry:Ensures efficient roller guidance, even stress distribution, low friction, and cooler running temperatures.
- Ease of Maintenance (Tapered Bore Design):Versions with a tapered bore and adapter sleeves facilitate easy mounting and dismounting on cylindrical shafts without shoulders.
Typical Applications
Spherical roller bearings are the workhorses in many heavy industries and demanding environments, including:
- Heavy Machinery: Mining equipment (crushers, mills), metallurgical plants (rolling mills), cement production (raw mills, kilns).
- Material Handling: Vibrating screens, large conveyors, bucket elevators.
- Power Generation: Wind turbine gearboxes, hydroelectric plants, gear reducers.
- Other Sectors: Paper machinery, marine propulsion systems, railway axle boxes (certain designs), support rollers, and general industrial driveshaft support.
