Circular Ring Roller Bearing
BORE 200-380mm
Circular ring roller bearings combines the self-aligning ability of the spherical roller bearings with the unconstrained axial displacement capability of the cylindrical roller bearings. The application field of this bearing covers a wide range regarding to radial loads. ZWA circular ring roller bearings contains the one with the cage or without the cage.
