Steel Cage W33 Spherical Roller Bearings Automotive Industry Use
Double spherical roller bearing, Description,
A spherical roller bearings is a rolling-element bearing that permits with low friction, and permits angular misalignment.
Typically these bearings support a rotating shaft in the bore of the inner ring that maybe misaligned in respect to the outer ring.
The misaligment is possible due to the spherical shape of the outer ring and spherical rollers.
