Clutch/Brake, CB4CW24VDC.38B6ST, Wrap Spring, Solenoid Operated, Standard, CB-4, CW Rotation, Hub Input, 0.376 / 0.378 in Bore, 6 Stop, 24 Vdc, 120 in-lbs Static Torque

Lead Time:  20 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
