Design Principles

The design principle of spherical ball bearings is that they have a spherical outer surface on the bearing outer ring, allowing the bearing to self-align within the bearing housing. This type of bearing typically includes a wide inner ring and an outer ring with a symmetrical spherical outer surface that fits into a corresponding spherical inner surface of the bearing housing. The bearing is usually attached to the shaft using an eccentric locking collar or sleeve. This design allows the bearing to self-adjust when there is misalignment or bending of the shaft, maintaining smooth operation.

Performance Features

The performance features of spherical ball bearings include:

• Self-aligning capability: Able to tolerate imprecise mounting and alignment deviations of the shaft.
• Easy to install: They can typically be mounted quickly and easily onto the shaft with an eccentric locking device.
• Suitable for light to medium loads: These bearings are suitable for applications with light to medium loads.
• Diverse housing options: Can be used with various types of bearing housings, such as pillow blocks, flanges, etc.
• Maintainability: Many types of spherical ball bearings are designed to be lubricated through lubrication holes, helping in maintenance and prolonging their service life.

Application Scenarios

Spherical ball bearings are suitable for a variety of scenarios, especially in the following cases:

• Agricultural machinery: In agricultural equipment, which often operates in harsh environments, and where the shafts may not be perfectly aligned.
• Food processing and packaging machinery: The bearings in these machines need to be regularly cleaned and lubricated.
• Conveying systems: On the support shafts of conveyors and roller conveyors, where there may be some misalignment and displacement.
• Textile machinery: In textile equipment, the bearings may need to be adjusted to accommodate the dynamics of machine operation.
• Wind power generation: In certain parts of wind turbines, where there may be shaft deflection.
