High Light NU312 cylindrical roller bearing 60x130x31mmheavy-duty cylindrical roller bearing for gear transmissionsingle row cylindrical roller bearing with warranty
1. Product Overview

NU312 is NU type single row cylindrical roller bearing. NU design features double ribs on outer ring and rib-free inner ring, allowing limited axial displacement between inner and outer rings. It can sustain heavy radial loads. The roller assembly can be separated from outer ring, facilitating convenient installation, disassembly and maintenance. Widely applied in heavy-duty gearboxes, mining conveyors, metallurgical rolling equipment, water pumps and various medium-speed heavy-load rotating assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.
