X-1353270.ND Non-Standard Auto Gearbox Precision Deep Groove Bearing

1. Product Overview

X-1353270.ND single-row non-standard deep groove ball bearing, suffix ND stands for upgraded precision tolerance and anti-deformation optimized structure. Fully interchangeable with original X-1353270.ND, specially matched for Asian passenger car automatic gearbox hydraulic control micro shafts. Multiple seal options: open, ZZ metal shield, 2RS double rubber seal. Equipped with stamped low-carbon steel cage, default C0 clearance, C3 clearance customizable on demand. It bears light radial load and slight bidirectional axial load, ultra-quiet stable high-speed running under high-temperature circulating gear oil inside transmission housing. Adopts fully quenched GCr15 bearing steel with strict micron dimensional tolerance, direct OEM plug-and-play replacement without modifying gearbox housing or micro shaft. Formal complete quotation provided within 24 hours after inquiry.

2. Key Advantages

• Open through-hole design enables full gear oil circulation, efficient continuous heat dissipation, eliminates hidden risks of rubber seal aging, swelling and oil leakage
• Superfinished smooth raceway reduces friction torque, less heat accumulation during long continuous high-speed operation
• ND upgraded precision structure with smaller dimensional deviation, stronger anti-deformation capacity under frequent tiny torque fluctuation
• High-hardness integrated inner and outer rings provide excellent wear resistance and anti-fatigue performance, extend gearbox service life
• Unified OEM installation size, no structural modification needed during shaft replacement
• Ultra-light stamped steel cage minimizes rotation inertia, fits long-term steady high-speed operation of miniature control components
• Standard P0 precision, P6 upgraded precision and C3 clearance customizable; stable mass production with sufficient stock, cost-effective for aftermarket and bulk OEM orders

3. Applications

Asian passenger car automatic gearbox hydraulic valve micro shafts, transmission auxiliary small rotating shafts, light commercial vehicle precision mini reducers, small agricultural machinery high-speed fine transmission parts.

8. FAQ

Q1: What do suffix ND mean?
A1: N = upgraded precision tolerance grade; D = reinforced anti-deformation internal structure, better stability under frequent variable light load.
Q2: Difference between open, ZZ and 2RS versions?
A2: Open for internal gearbox circulating oil lubrication; ZZ metal shield for semi-sealed inner assembly; 2RS double rubber seal for external exposed shafts, dustproof and waterproof with pre-filled grease.
Q3: Can X-1353270.ND replace original bearing directly?
A3: Yes, all mounting dimensions and internal structure fully consistent, no modification to gearbox parts required during assembly.
