High Light GQZ NU312 cylindrical roller bearing 60x130x31mm ,heavy-duty cylindrical roller bearing for gear transmission ,single row cylindrical roller bearing with warranty
1. Product Overview

NU312 belongs to NU-type single row cylindrical roller bearing. The structure 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 only. The roller and inner ring assembly can be separated from outer ring, bringing convenience for assembly, disassembly and routine maintenance. Widely applied in heavy-duty gearboxes, large water pumps, compressors, mining conveyors and medium-heavy load rotating assemblies.

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