Stainless Steel Spherical Roller Bearings Low Friction Separable
Description Spherical Roller Bearing,
A spherical Roller bearings is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment,
Typically these bearings support a rotating shaft in the bore of the inner that may be misaligned in respect to the outer ring.
The misalignmets is possible due to the speherical internal shape of the outer ring and spherical rollers.
