GQZ F-201380.RNU Full Complement Cylindrical Roller Bearing 30.4×52×22mm For Printing Machine And Hydraulic Equipment

F-201380.RNU is special full complement single row cylindrical roller bearing. RNU construction means without inner ring, outer ring with double ribs. The shaft journal is directly used as rolling raceway after quenching and precision grinding. Full roller layout maximizes roller quantity to achieve extraordinary radial load capacity. It allows limited axial floating movement, mainly withstand heavy radial load. Widely used for Heidelberg printing press rollers, hydraulic pump rotor supporting positions and special compact gearbox transmission assemblies.

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

1. RNU no-inner-ring structure, save radial installation space, simplify overall equipment structural layout
2. Full complement roller arrangement, maximum number of rollers, outstanding heavy radial load & impact resistance
3. Outer ring double ribs limit roller assembly falling off, allow slight axial floating compensation
4. Requires hardened & ground shaft surface to serve as inner raceway, compact assembly solution
5. Optimized roller contour, low vibration and stable operation under medium continuous load
6. Customizable options: OEM laser marking, special clearance, high-temperature strengthening treatment
7. Stable performance to reduce downtime for printing and hydraulic machinery.
