Hydraulic release bearing

The hydraulic release bearing design adds bearing self-aligning in the design, hydraulic pump body, the bearing is pushed by the hydraulic cylinder body during use, and the force is stable, thus ensuring smoother clutch engagement, softer separation, reducing wear, and extending the clutch and the entire transmission system. The purpose of the service life.
