The lifespan of automotive bearings affects vehicle safety and operating costs, especially for commercial vehicles.
Case Details
For passenger car wheel hub bearings, we use GCR15 bearings as raw materials, undergoing salt bath bainitic heat treatment. The bearing rings undergo double-grinding for ultra-precision machining, and the steel balls are G10 standard steel balls. We have a complete testing system, including hardness testing, radial clearance testing, axial clearance testing, and precision and surface roughness testing.
We offer an 80,000 km warranty. For commercial truck and trailer wheel hub bearings, we use double-row tapered roller bearings. In addition to adopting the production technology of passenger car bearings, we have upgraded and optimized the oil seals and their accessories. The oil seals adopt a box-type structure, using NBR and FKM materials as raw materials. We strictly control the vulcanization time, resulting in better sealing performance, significantly improved weather resistance, and excellent corrosion resistance. We offer a 200,000 km warranty.
