Spherical Rollers

Spherical rollers have a spherical rolling surface. Bearings with such rollers have self-aligning properties and can withstand large loads. Spherical rollers are divided into asymmetric type and symmetric shape, generally asymmetric large end surface for the spherical surface, symmetric shape of the two end surfaces for the flat end surface.

Characteristics of spherical rollers

Strong load-bearing capacity: Spherical roller bearings have large contact area and can withstand large radial loads.

Low friction: Due to the principle of rolling friction, spherical roller bearings have less friction and higher efficiency than sliding bearings.

High precision: Some high-precision spherical rollers can be used in high-speed and precision equipment.

When choosing a spherical roller, the following factors need to be considered:

Load requirements: Choose the appropriate specifications according to the load required.

Speed requirements: When running at high speed, choose rollers made of materials that are suitable for high speeds.

Temperature and environment: Choose appropriate materials and sealing methods according to the temperature and pollution conditions of the working environment.

Lubrication: Reasonable lubrication can reduce friction and extend the service life of the bearing.
