Product Process Introduction
The grinding process is the most crucial production of wheel hub bearings.
Our ballrace grinding process for inner ring, outer ring and flange is engineered to meet the strict OEM and aftermarket performance standards.
Using high-precision CNC ballrace grinding machines, we perform twice superfinishing on every ballrace, this dual process achieving ultra-precise control over key parameters including ballrace position, curvature, roundness, parallelism, and surface roughness down to the micron level.
Every part undergoes 100% in-process inspection by specialized equipment like height gauges, roughness testers, roundness meters, and contour gauges.
These rigorous controls ensure the ballraces burn-free status, surface texture, corrosion, or harmful scratches, minimizing friction, reducing noise, and preventing premature wear.
This level of precision directly translates to improved load distribution, enhanced fatigue resistance, and extended service life of the entire wheel hub bearings.


Research and Development Process
Mechanical Reliability: Multi-functional bench tests to validate product lifespan and performance.Zero-Defect Assurance: 100% inspection with magnetic particle testing, noise checks, and ABSfunctionality tests.
Full Traceability System
Each wheel hub is marked with a laser-etched QR code for full batch tracking. We retain test data forover 2 years and provide detailed inspection reports. Factory audits are always welcome.
