High Light Single Row Cylindrical Roller Bearing 90×160×52.4mm ,Industrial Gearbox Cylindrical Roller Bearing ,Heavy Machinery Cylindrical Roller Bearing
1. Product Overview

NJ5218 is single row cylindrical roller bearing with one rib on inner ring and two ribs on outer ring. This NJ structure enables bearing to carry heavy radial load and limited one-way axial load. The inner ring, roller and cage assembly can be separated from outer ring, facilitating independent installation and maintenance. Widely used for industrial reducers, gearboxes, construction machinery and heavy transport transmission assemblies.

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

2. Technical Specifiions
