NTN UC321D1 Radial Insert Ball Bearing 105 mm

Overview

NTN UC321D1 Radial Insert Ball Bearing is an easy-mount ball bearing used in housing units or directly fixed on shafts. Based on deep groove ball bearing geometry, it adds locking devices and seals to simplify maintenance in agricultural machines, conveyors, fans, and handling equipment.

A spherical outer ring and shaft-locking device allow the bearing to compensate for static misalignment when combined with a matching housing. Sealed and lubricated variants are suitable for dusty or wet operating environments.
