HTFB31-16A1 Open Deep Groove Auto Gearbox Bearing

HTFB31-16A1 non-standard open deep groove ball bearing, size 31×80×16mm, upgraded version of HTFB31-16 for auto manual and automatic gearbox differential and intermediate shafts. Open design without rubber seals, matched stamped steel cage and C0 standard clearance. It bears radial load and slight bidirectional axial load, stable low-noise high-speed operation under frequent shifting vibration. Made of fully quenched high-purity GCr15 steel with tighter dimensional tolerance, fully interchangeable with original HTFB31-16A1. Complete formal quotation will be provided within 24 hours upon inquiry.

• Open design enables smooth gear oil circulation and good heat dissipation, no rubber seal aging risk under long-term high temperature oil soaking
• Optimized superfinished raceway, lower friction coefficient, stable running under continuous gear shifting impact
• High-hardness purified GCr15 steel with excellent wear and fatigue resistance, prolong transmission service life
• Upgraded dimensional tolerance for higher assembly matching accuracy, direct replacement without modifying gearbox parts
• Light stamped steel cage reduces rotation inertia, fits continuous medium-high speed transmission working conditions
• Standard P0 precision, P6/C3 clearance customizable to meet vehicle OEM assembly standards

Q1: What is the difference between HTFB31-16A1 and HTFB31-16?
A1: HTFB31-16A1 adopts tighter dimensional tolerance control, higher assembly precision, suitable for high-precision gearbox matching requirements.
Q2: Difference between open bearing and rubber sealed bearing?
A2: Open structure has no rubber seals, relies on circulating gear oil for lubrication and cooling for internal gearbox positions; sealed bearings apply to external dusty shafts with grease lubrication.
Q3: Can HTFB31-16A1 replace original bearing directly?
A3: Yes, inner bore, outer diameter and width dimensions are fully consistent, no modification to gearbox housings or shafts needed.
