Warner CB Series Clutch/Brake 302-27-003

SERIES DESCRIPTION

The Warner Electric CB Series combination clutch/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 ±1/2° noncumulative at speeds up to 1800 RPM depending on size. Each unit is pre-engineered and pre-assembled for easy installation.

FEATURES

• Adjustable control collars for easy and accurate output stop position setting.
• Load over-travel or backup is eliminated since CB units lock the load in both directions when the solenoid is off.
• Anti-overrun feature prevents the output from running faster than the input.
• Permanently lubricated—never needs adjustment for wear.
• Brings load up to speed in 3 milliseconds and stops within 1.5 milliseconds.

SELECTION PROCEDURE

1. Step 1: Determine the clutch or brake function—Wrap spring clutches and brakes can perform three control functions overrunning, start-stop and single revolution. Determine the function that will provide the best control for your application.
2. Step 2: Determine the size—To select the correct size unit, determine the maximum RPM at which the clutch or brake will operate and the shaft diameter on which the wrap spring unit will be mounted. Locate the appropriate speed and shaft diameter points on the selection charts.
3. Step 3: Verify the design function considerations—Once the appropriate series and model size have been determined, review the design considerations and the checklist of options detailed in the “How to Order” section for each series.

HOW TO ORDER

• Specify Model Configuration: Reference model number 302-27-003 or use ordering code CB-2-CCW-24VDC-1/4″-4.
• Verify Voltage and Rotation: Confirm your system matches the 24V DC power requirement and counter-clockwise (CCW) direction.
