Clutch Release Bearing 40TMK20B1

Clutch Release Bearing 40TMK20B1 is a precision-engineered component designed to facilitate seamless engagement and disengagement of power transmission in automotive and industrial clutch systems. Specifically optimized for high-performance applications, this bearing integrates advanced self-aligning technology to compensate for misalignments between the diaphragm spring and the transmission input shaft, ensuring consistent contact and reducing heat generation during sudden rotational shifts. Constructed with premium-grade chrome steel (GCR15) for the inner and outer races, it delivers exceptional wear resistance and structural integrity under dynamic loads, while the nylon-reinforced cage enhances rotational stability and minimizes friction. The bearing features a dual-sealed design with nitrile rubber (NBR) barriers and high-temperature grease lubrication, effectively repelling contaminants and maintaining lubrication integrity in harsh operating environments. This configuration supports reliable operation across a broad range of vehicles, including heavy-duty trucks, racing cars, and agricultural machinery, where durability and precision are critical.

Designed for compatibility with hydraulic clutch systems, the 40TMK20B1 ensures smooth pedal response and reduced operating noise through its balanced roller dynamics and low-friction contact surfaces. Its compact yet robust construction incorporates a self-centering mechanism that absorbs axial and radial forces, preventing premature wear and extending service life even under extreme temperature fluctuations and high-speed rotations. The bearing’s engineering plastic sleeve, reinforced with MOS2 coating, offers enhanced sliding performance and corrosion resistance, while the elastomeric seals and built-in grease reservoir provide maintenance-free operation over extended periods. By integrating OE-compliant design principles, this bearing meets stringent quality standards for both original equipment and aftermarket applications, ensuring seamless integration and optimal performance in demanding industrial and automotive environments.
