Clutch Release Bearing Assembly

When pressing the clutch pedal, how light the feel is and how complete the disengagement is depends largely on the release bearing assembly. It is the only component in the clutch control system that combines both rotation and sliding-it must rotate at high speed with the diaphragm spring while moving back and forth axially, under harsh conditions. A substandard release bearing causes, at best, stiff or noisy pedal operation, and at worst, incomplete disengagement, gear grinding, or even burnt clutch plates. We make Clutch release bearing assemblies to get this small-part, big-impact component right.

We use high-carbon chromium bearing steel for bearing rings, heat-treated to HRC 60–64, with raceways super-finished for smooth rotation and low noise. The bearing housing is made of high-strength aluminum alloy or stamped steel-lightweight yet rigid. The inner bore guide surface is precision bored and honed for low sliding resistance. After assembly, 100% rotation testing and axial play detection ensure smooth rotation with no sticking or noise. Clutch release bearing assemblies are used in clutch systems of passenger vehicles, commercial vehicles, and agricultural machinery, covering specifications from microcars to heavy trucks. Every batch undergoes sampling life testing, and material reports and assembly inspection records can be provided. Years of automotive parts manufacturing, OEM supply history, stable process. After years of making Clutch release bearing assemblies, our insight is that consistency matters more than single-piece precision for this part-that is why 100% rotation testing after assembly ensures every piece rotates smoothly and quietly. Send us drawings or samples; verify with samples first.

Operating under IATF 16949. Bearing rings: hardness testing (HRC 60–64) and rotational precision testing; raceway surface roughness sampled. After assembly: 100% rotation testing for smooth, no-sticking, no-noise operation; axial play detection controlled within drawing requirements. Every batch: sampling life testing, assembly inspection data accompanies goods. OEM supply history, stable process. Third-party inspection per customer specification accepted.

Customization from drawings and samples supported. Bearing specification, housing structure (aluminum alloy or stamped steel), installation dimensions, sealing form all adjustable per drawing, no strict MOQ. Pedal feel tuning supported-sliding resistance and release travel optimized per requirement. Custom samples typically 15–20 working days, shorter for simple processes. Small sample fee charged, fully deductible against bulk orders. Sample first to verify release performance and pedal feel, then scale up.
