Features:

  • Steel cages
  • Hardend steel shells
  • High temperaure grease
  • Standard release bearing
  • Outer race rotates
  • Inner Diameter options:
    • Ø35mm
    • Ø40mm

Release Mechanism

As the spring rate and clamp load of the clutch increases, so does the release bearing load required to release the clutch. The release bearing used is a high quality steel caged radius contact ball bearing; either 38mm, 45mm, 50mm or 54mm in diameter. The release mechanism should be arranged so that the bearing is free of the spring fingers when the clutch is fully engaged. The release travel should be limited by means of an external stop to avoid damage to the diaphragm spring.
