For best performance when clutch is used as Master or Operating clutch - limit use to 75% of maximum input torque and derate for apply pressures less than 130 psi.

  • Class I = Disconnect
  • Class II = Light Duty
  • Class III = Normal Duty
  • Class IV = Heavy Duty

Maximum Speeds listed are safe permissible speeds possible with cast iron driving rings. The driving ring is normally the most critical member because it has the largest diameter. Please note that the maximum speed is usually set considerably above the desired operating speed in the average installation.
