B37-9AUR Open UR Groove Auto Gearbox Deep Groove Bearing

B37-9AUR non-standard open deep groove ball bearing, dimension 37mm bore × 85mm outer diameter × 13mm width, specially matched for passenger car automatic and manual gearbox auxiliary shafts and differential assemblies. Open design without rubber seals, outer ring integrated UR snap ring groove for axial positioning, fitted with stamped steel cage and standard C0 clearance. It bears radial load and slight bidirectional axial load, runs stably and quietly under long-term high-speed shifting vibration. Made of fully quenched GCr15 chrome bearing steel with precise dimensional tolerance, fully interchangeable with original B37-9AUR. Complete formal quotation will be provided within 24 hours upon inquiry.

• Open structure enables full circulation of gearbox oil, excellent heat dissipation, no rubber seal aging or swelling risk under long-time high-temperature oil immersion
• Outer ring built-in UR retaining ring groove, install circlip directly for axial limit, simplify assembly without extra limiting components
• Superfinished deep groove raceway reduces rolling friction, stable operation under continuous gear shift impact
• High-hardness purified GCr15 steel delivers outstanding wear and anti-fatigue performance to extend gearbox service life
• OEM matching overall dimension, direct replacement without modifying gearbox housing and shaft parts
• Light stamped steel cage lowers rotation inertia, adapts to continuous medium-high speed transmission working conditions
• Standard P0 precision grade, customizable P6/C3 clearance to meet vehicle OEM assembly standards

Passenger car automatic & manual gearbox intermediate shafts, vehicle differential assemblies, light commercial vehicle reducers, small agricultural machinery transmission components.

Q1: What does suffix UR mean on B37-9AUR?

A1: UR stands for precision circlip groove machined on outer ring, used together with retaining ring to restrict bearing axial displacement inside gearbox housing.

Q2: Difference between open B37-9AUR and rubber sealed bearings?

A1: Open design has no rubber seals, relies on circulating gear oil for lubrication and heat dissipation for internal gearbox positions; rubber sealed bearings apply to external dusty shafts with grease lubrication.

Q3: Can B37-9AUR replace original OEM bearings directly?

A3: Yes, inner bore, outer diameter, width and UR groove sizes are fully consistent, no modification to gearbox components required during replacement.
