Precision engineering and material selection are paramount in the CKZ-D Series One Way Overrunning Clutch. Key components are manufactured from high-grade alloy steels, often case-hardened or through-hardened, to ensure maximum wear resistance and fatigue strength. The sprags themselves are typically made from chrome steel or other specialized alloys, heat-treated to achieve optimal hardness and resilience. The design of the sprag geometry is critical for efficient engagement, minimal backlash, and long service life, reducing stress concentrations and ensuring uniform load distribution. Advanced sealing mechanisms protect internal components from contaminants, extending the operational lifespan even in challenging environments.
