22217 EC3 Bearing Short Description

22217 EC3 bearing has double-row rollers, the outer ring has a common spherical raceway. And the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easy to be affected by the angle of the shaft.

It is suitable for occasions where the installation error or the shaft deflection causes the angle error. In addition to the radial load, the bearing can also withstand the axial load acting in both directions.

Spherical roller bearings have cylindrical and conical bores. The taper of the conical bore is 1:30 and 1:12. This conical bore bearing has an adapter sleeve or a withdrawal sleeve.

22217 EC3 Spherical Roller Bearing Features

Self-aligning function
Spherical roller bearings accommodate misalignment between the shaft and housing without increasing friction or reducing bearing service life.

It has a Very high load-carrying capacity
Optimized internal geometry within the available cross-section provides maximum radial and axial load carrying capacity.

Robust bearing structure
Insensitive to misalignment caused by shaft or housing deflections as a result of heavy loads.

It can easily fit for loads in all directions
The bearings are non-separable and ready to install. Therefore, it has its own mounting methods.
