HTFB29-11NX Open NX Groove Auto Gearbox Deep Groove Bearing

HTFB29-11NX non-standard open deep groove ball bearing, dimension 29mm bore × 78mm outer diameter × 19mm width, special HTFB transmission series, matched for Honda automatic gearbox input and differential shafts, interchange OE number 91002-RPC-005. Open design without rubber seals, outer ring integrated NX precision circlip groove for axial positioning, fitted stamped steel cage and C0 standard clearance. It bears radial load and minor bidirectional axial load, stable low-noise high-speed operation under frequent shifting vibration. Made of fully quenched high-purity GCr15 chrome steel with tight dimensional tolerance, fully interchangeable with original OEM HTFB29-11NX. 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/swelling risk under long-time high-temperature oil soaking
• Outer ring built-in NX retaining ring groove, install circlip directly for axial limit, simplify assembly without extra limiting components
• Superfinished deep groove raceway reduces rolling friction, stable continuous operation under frequent gear shift impact
• Uniform high-hardness GCr15 steel delivers outstanding wear and anti-fatigue performance to extend gearbox service cycle
• OEM matching integral dimension, direct replacement without modifying gearbox housing and shaft parts
• Lightweight stamped steel cage lowers rotation inertia, adapts to medium-high speed continuous transmission working conditions
• Standard P0 precision grade, customizable P6/C3 clearance to meet Honda OEM assembly matching standards

Honda automatic gearbox input shafts, passenger car differential assemblies, light commercial vehicle reducers, small agricultural machinery transmission components.

Q1: What does suffix NX mean on HTFB29-11NX?
A1: NX stands for precision circlip groove machined on outer ring, matched with retaining ring to restrict bearing axial displacement inside gearbox housing.

Q2: Difference between open HTFB29-11NX 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 HTFB29-11NX replace original Honda OEM bearings directly?
A3: Yes, inner bore, outer diameter, width and NX groove sizes are fully consistent, no modification to gearbox components required during replacement.
