Self Adjusting Clutch Ring   Industry Automotive Material Stanyl® TW200F6 - PA46-GF30   Processing Technology Injection Molding Description Stanyl® provides outstanding high-temperature performance over the 100,000 mile life expectancy of the vehicle, including dimensional stability, resistance to compressive creep, and chemical resistance. The self-adjusting clutch allows pedal efforts to remain constant as the clutch disk wears. Its spring-loaded thermoplastic ring features serrations which are wedged forward to maintain the proper gap between the pressure plate and cover fulcrums, resulting in a consistent feel for the driver throughout the vehicle's life. The self-adjusting feature fully eliminates traditional threaded/cable mechanisms for manual clutches, thus reducing maintenance and associated costs. Dimensional tolerances for the serrations are extremely narrow, and the low post-mold shrinkage of Stanyl® was sited as a critical factor in its selection. In addition, maximum deflection of .3mm under a 8,000N load requires tremendous dimensional stability over the life of the part.
