B60-57NXUR NXUR Double Lip Sealed Non-Standard Deep Groove Ball Bearing, Auto Gearbox Special Bearing
B60-57NXUR non-standard deep groove ball bearing customized for automobile and agricultural machinery gearboxes, overall dimension 60mm bore × 101mm outer diameter × 17.2mm width. Double-sided NXUR reinforced contact rubber seals effectively block external dust, mud splashes and prevent internal gear oil leakage. Standard C0 internal clearance, deep groove raceway bears radial load and bidirectional light axial load, stable low-noise high-speed rotation under frequent gear shifting vibration. Adopts fully quenched GCr15 bearing steel, unified dimensional tolerance, fully interchangeable with original matching bearings. Complete formal quotation will be provided within 24 hours upon inquiry.
- Upgraded NXUR double-layer contact rubber sealing structure, excellent dust-proof and oil-proof performance, adapt to semi-sealed gearbox internal working environment, reduce oil loss and dirt invasion.
- Optimized deep groove raceway design, low rotation friction, stable operation under continuous shifting impact and long-term vibration.
- High hardness full heat-treated GCr15 chrome steel, outstanding wear resistance and fatigue resistance, extend service life of transmission assembly.
- Special non-standard overall size consistent with original gearbox housing, direct replacement without modifying shaft and box parts.
- Lightweight stamped steel cage, small rotation inertia, suitable for medium-high speed continuous transmission operation.
- Optional P0/P6 precision grades, fully meet vehicle OEM assembly matching standards.
Automotive manual & automatic gearbox auxiliary shafts, farm tractor transmission assemblies, light commercial vehicle reducers, medium-speed agricultural machinery transmission components, general industrial gear reduction devices.
