NCB35-149.A Open High Precision Auto Gearbox Deep Groove Bearing

NCB35-149.A non-standard open single row deep groove ball bearing, dimension 35mm bore × 62mm outer diameter × 12mm width, NCB dedicated transmission series with A high-precision tolerance upgrade. Open structure without rubber seals, equipped with stamped steel cage and standard C0 internal clearance. It supports radial load and minor bidirectional axial load, running smoothly and low-noise under long-duration high-speed shifting vibration. Manufactured with fully quenched high-purity GCr15 chrome steel and tight dimensional tolerance control, fully interchangeable with original OEM NCB35-149.A. Complete formal quotation will be supplied within 24 hours upon inquiry.

• Open layout allows full flow of gearbox oil, excellent heat dissipation, no rubber seal aging or swelling failure under long-term high-temperature oil immersion
• A-grade upgraded geometric tolerance, higher roundness and raceway finish, matching high-precision automatic transmission assembly standards
• Superfinished deep groove raceway reduces rolling friction, stable continuous operation under frequent variable-speed impact
• Uniform high-hardness GCr15 steel delivers outstanding wear resistance and anti-fatigue performance, extending gearbox service life effectively
• OEM unified overall dimensions, direct replacement without modifying gearbox housing and shaft components
• Lightweight stamped steel cage cuts rotation inertia, suitable for medium-high speed continuous transmission working conditions
• Standard P0 precision grade, P6/C3 clearance customizable to meet automotive OEM assembly requirements

Passenger car automatic gearbox auxiliary and intermediate shafts, small CVT transmission assemblies, light commercial vehicle reducers, mini agricultural machinery transmission parts.

Q1: What does suffix A stand for on NCB35-149.A?
A1: A represents upgraded tight tolerance standard, higher dimensional and geometric precision for high-matching automatic gearboxes.

Q2: What is the difference between open NCB35-149.A and rubber sealed bearings?
A1: Open design has no rubber seals, relying on circulating gear oil for lubrication and cooling inside gearboxes; rubber sealed bearings apply to external dusty shafts with grease lubrication.

Q3: Can NCB35-149.A replace original OEM bearings directly?
A3: Yes, inner bore, outer diameter and width dimensions are fully consistent, no modification to gearbox components required during replacement.
