FAQ
1. What vehicle models are your drive shaft bearings suitable for?
Our new energy drive shaft bearings cover a full range of mainstream domestic new energy vehicle models, including Changan, Changan Oushang X5/X7, Hongqi H5, BYD Han/Tang/Song, Xpeng P7, Li Auto, Chery, GAC and Geely Lynk & Co 06. We support targeted bearing model matching for different vehicle platforms.
2. Do you need different bearing structures for different car models?
The core structural design remains consistent across all models. We adopt different customized specifications and dimensional parameters to match the installation size, chassis tolerance and power output requirements of different vehicle models. It features strong universality and high compatibility.
3. What are the core performance requirements for new energy drive shaft bearings?
New energy vehicle drive shaft bearings face stricter working conditions than traditional fuel vehicle bearings, requiring six core performances:
High dimensional accuracy & low runout, professional NVH noise reduction performance, excellent high-temperature thermal stability, strong anti-fatigue and impact load resistance, reliable all-weather sealing, and long service life for high-frequency driving.
4. Why do new energy drive shaft bearings require low noise and low vibration?
New energy vehicles have no engine noise, so chassis and transmission noise are more perceptible. Our bearings adopt ultra-precision grinding and optimized raceway design, effectively reducing operating vibration and abnormal noise, fully meeting the high-standard NVH comfort requirements of new energy passenger vehicles.
5. Why is high temperature resistance critical for drive shaft bearings?
New energy vehicles feature high motor speed, frequent acceleration and deceleration, and continuous high-load operation, which generate massive heat on the drive shaft. Professional high-temperature resistant structure and special grease prevent lubricant carbonization, dry friction and bearing seizure, maintaining stable precision during long-term high-speed operation.
6. What load resistance do your drive shaft bearings support?
They are designed for complex road conditions and driving states. The bearings can withstand alternating radial load, axial thrust load and instantaneous road impact load, with excellent structural rigidity and anti-fatigue performance, adapting to daily commuting, high-speed driving and bumpy road conditions.
7. How do your bearings adapt to complex driving environments?
Equipped with upgraded sealing structure, the bearings effectively isolate dust, rainwater, mud and airborne impurities. They avoid internal corrosion, grease leakage and abrasive wear, realizing stable all-weather operation and greatly extending the overall service life of the drive shaft assembly.
