B75-57 Open Non-Standard Auto Transmission Deep Groove Bearing

1.Product Overview

B75-57 non-standard single-row open deep groove ball bearing, dimension 75mm inner bore × 106mm outer diameter × 12mm width, fully interchangeable with original NSK B75-57 transmission bearing, specially matched for ninth generation Accord automatic gearbox main shaft and differential assemblies. Open design without rubber seals, equipped with stamped low-carbon steel cage and factory standard C0 internal clearance. It bears radial load and slight bidirectional axial load, maintains stable low-noise high-speed rotation under long-term shifting vibration inside gearbox housing. Produced with fully quenched high-purity GCr15 chrome bearing steel and strict dimensional tolerance control, fully compatible with OEM B75-57 assembly requirements. Complete formal quotation will be provided within 24 hours upon inquiry.

2.Key Advantages

• Open structure enables full circulation of gearbox transmission oil, outstanding heat dissipation performance, eliminates aging, swelling and leakage risks of rubber seals under long-time high-temperature oil soaking
• Superfinished deep groove raceway reduces rolling friction coefficient, stable continuous rotation under frequent gear shift and variable-speed impact
• Uniform high-hardness GCr15 raw steel delivers outstanding wear resistance and anti-fatigue performance, effectively extend automobile transmission service cycle
• OEM unified matching overall dimension, direct replacement without modifying gearbox housing, shaft and assembly accessories
• Lightweight stamped steel cage lowers rotation inertia, perfectly fits medium-high speed continuous working conditions of vehicle transmissions
• Standard P0 precision grade, P6 / C3 clearance customizable to meet mainstream auto OEM assembly matching standards
• Stable mass production supply, cost-effective for aftermarket repair and bulk wholesale orders

3.Applications

9th generation Honda Accord automatic gearbox intermediate main shafts, passenger car transmission differential assemblies, light commercial vehicle reducers, large agricultural machinery transmission components.

8.FAQ

Q1: Difference between open B75-57 and rubber sealed bearings?

A1: Open structure has no rubber sealing parts, relies on internal gearbox circulating oil for lubrication and heat dissipation, installed inside transmission housing; rubber sealed bearings are used for external exposed dusty shafts with grease lubrication.

Q2: Can B75-57 replace original NSK OEM bearings directly?

A2: Yes, inner bore, outer diameter and width dimensions are fully consistent, no modification to gearbox components required during replacement.

Q3: Applicable lubrication mode?

A3: Designed for gearbox circulating transmission oil lubrication; fill high-speed anti-wear gear grease if used separately for independent assembly.
