INShine 22206C 22206CK Spherical Bearing With Symmetrical Rollers, Asymmetrical Rollers

We can produce the diameter from 20mm~1  800mm  spherical roller bearings. 25mm~220mm  sealed spherical roller bearings etc. Following is the internal structure of KMR different product descriptions.
 
spherical roller bearings are self-aligning function, but is also very strong. Spherical Roller Bearings are two rows of rollers, in the outer ring, there is a sharing of spherical roller Road, there are two Inner Raceway, with the bearing axial tilt into a relative perspective. This is the bearing attractive design features, in many demanding applications can not be replaced.  spherical roller bearings are open, sealed and applied to the specific application of bearings.
