III. Product Advantages
✅ Specialized Seal Structure for Gearboxes
Customized gearbox oil-resistant seals, resistant to oil corrosion, preventing lubricant leakage, and suitable for long-term gear oil immersion conditions.
✅ Balanced Load Bearing, Resistant to Alternating Loads
Deep groove ball bearing structure, simultaneously bearing radial loads and bidirectional axial loads, adapting to gearbox shift shocks.
✅ High Operating Precision and Low Noise
Precision raceway machining results in low vibration at high speeds, meeting the quiet operation requirements of passenger car gearboxes.
High Temperature Resistance and Long Lifespan
✅ Special heat treatment process ensures good dimensional stability under prolonged high-temperature conditions, reducing the risk of premature fatigue spalling.
⚠️Note: This is a non-standard automotive bearing; standard 62XX/63XX deep groove ball bearings cannot be directly replaced.
