GQZ NU212 Single Row Cylindrical Roller Bearing 60×110×22mm Separable Inner Ring Heavy Radial Load Industrial Roller Bearing
- NU212 is an open single-row cylindrical roller bearing with dimension 60×110×22mm featuring NU separable inner ring structure. It has outstanding heavy radial load capacity and allows independent disassembly of the inner ring, simplifying shaft installation and maintenance. W33 lubriion groove, brass cage and C3 enlarged clearance can be customized to fit heavy machinery working conditions. It runs stably at medium speed and widely applied to gearboxes, mining and construction equipment.
