Clutch release bearings work at a high speed, high temperature and strong vibration in a long term. It is more important that result in temperature raising faster, stronger vibration and wear quickly when release bearings in operation, and affect service performance and service life of release bearings and the clutch, due to installation eccentricity of the engine crankshaft and transmission input shaft, or of clutch on the flywheel. Based on the self-aligning structure of wave springs, the structure of high bearing capacity of thrust angular contacting ball bearing, and the innovative process design of bearing inner and outer races, we have developed automobile clutch self-aligning release bearings with less vibration, low noise, wear light, long life (for separating more than 2 million times and no failure).
