X-1353248.ND Non-Standard Auto Gearbox Precision Deep Groove Bearing

1. Product Overview

X-1353248.ND single-row non-standard thin-wall deep groove ball bearing. Suffix ND represents upgraded precision tolerance plus reinforced anti-deformation internal structure. Fully interchangeable with NSK X-1353248.ND, specially designed for miniature hydraulic valve shafts inside Asian passenger car automatic transmissions.
Available versions: Open, ZZ metal shield, 2RS double rubber seal. Adopts stamped low-carbon steel cage, standard C0 clearance as default, C3 clearance customizable. It bears light radial load and slight bidirectional axial load, running ultra-quiet and stable under long-term high-speed rotation and high-temperature circulating gear oil environment inside transmission housing. Produced with fully quenched GCr15 chrome bearing steel and strict micron-level dimensional tolerance, supports direct OEM plug-and-play replacement without modifying gearbox housing or micro shaft. Complete formal quotation available within 24 hours upon inquiry.

2. Key Advantages

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

3. Applications

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

8. FAQ

Q1: What do suffix N and D stand for?
A1: N = upgraded precision tolerance grade for tighter fit; D = reinforced internal structure with stronger anti-deformation capacity under frequent variable light load.
Q2: Difference between open, ZZ and 2RS types?
A2: Open for internal gearbox circulating oil lubrication; ZZ metal shield for semi-sealed internal assembly with light dust; 2RS double rubber seal for exposed external shafts, dustproof & waterproof, pre-filled long-life anti-wear grease.
Q3: Can X-1353248.ND replace original NSK bearing directly?
A3: Yes, all mounting dimensions and internal structure are fully consistent, no modification to gearbox components needed during assembly.
