Rex ZB-2115 Bearing

Rex ZB2115 is a 1-15/16 in bore spherical roller bearing unit mounted in a flanged block, part of Rexnord’s fixed normal-duty ZB family. The housing is cast iron and accepts a 1-15/16 in shaft diameter, secured on the shaft with a single-set collar and a nominal 1/16 in standoff. This flange-block configuration is designed for surface mounting and provides a robust mounting interface for cylindrical shafts in compact installations. Available dimensional references for the ZB2115 family include bolt center-to-center spacing from 6-1/16 to 7-1/4 in, a base-to-bore centerline distance of 2-1/4 in, and overall dimensions of 8-7/8 in length by 4-9/16 in height, aligning with Rexnord 2000-series product specifications for fixed normal-duty spherical roller bearing units.
