B40-167A Open Non-Standard Deep Groove Ball Bearing, Auto Gearbox Special Bearing

B40-167A is a non-standard open deep groove ball bearing with dimension 40mm inner bore × 90mm outer diameter × 19mm width, matching vehicle and tractor gearbox differential assemblies. Open design without rubber seals, fitted with stamped steel cage and C0 standard internal clearance. It bears radial load and bidirectional light axial load, stable low-noise high-speed operation under frequent shifting vibration. Fully quenched GCr15 bearing steel with precise dimensional tolerance, fully interchangeable with original HTF B40-167A. Formal quotation will be provided within 24 hours upon inquiry.

• Open structure enables full circulation of gearbox lubricating oil, excellent heat dissipation, stable high-speed operation inside transmission housings, no rubber seal aging failure risk.
• Deep groove raceway design bears combined radial and slight axial force, low friction coefficient and quiet running under continuous gear shifting impact.
• Uniform high-hardness GCr15 chrome bearing steel, outstanding wear resistance and fatigue resistance, greatly extend gearbox service cycle.
• Customized integral dimension consistent with original gearbox housing, direct replacement without modifying shafts or box components.
• Lightweight stamped steel cage reduces rotation inertia, adapts to long-term medium-high speed continuous transmission working conditions.
• Optional P0/P6 precision grades, fully meet OEM vehicle transmission assembly matching standards.

Automotive manual & automatic gearbox differential shafts, farm tractor transmission assemblies, light commercial vehicle auxiliary reducers, medium-speed agricultural machinery transmission parts, general industrial gear reduction devices.
