Clutch/Brake, CB8CW115AC1.38B1ST, Wrap Spring, Solenoid Operated, Standard, CB-8, CW Rotation, Hub Input, 1.3755 / 1.3775 in Bore, 1 Stop, 115 Vac, 2500 in-lbs Static Torque

Lead Time:  5 Days

  • CB Series combination clutches and brakes accurately start and stop loads driven by a continuously rotating power source. CB units operate from a single AC or DC pulse, stopping the load within ±½° noncumulative at speeds up to 1800 RPM, depending on size.
  • Adjustable control collars for easy and accurate output stop position setting
  • Load over-travel or back-up is eliminated since CB units lock the load in both directions when the solenoid is off
  • Permanently lubricated—never needs adjustment for wear
  • Brings load up to speed in 3 milliseconds and stops within 1.5 milliseconds
  • RoHS compliant
