Designed to withstand the high spring pressure & high RPM common to race clutches, bearing faces are heat-treated and Blanchard ground to ensure trueness. Collars are machined to close tolerances for secure bearing fork attachment and heat-treated for strength. Ball bearing races are filled with heat-resistant moly-based grease for better lubrication and longer life while nylon liners and bearing retainers provide cooler, quieter operation.
Self-Aligning Throwout Bearings
Developed for installations with clutch-to-transmission misalignment resulting in noise and vibration, self-aligning throwout bearings minimize such conditions (clutch alignment can also vary due to normal usage). Rugged self-aligning bearings can be an upgrade from standard bearings when applicable on older cars.
