Friction Brakes

This spring applied brake is electromagnetically released and can be used either dry or in oil depending on the type of friction material used.

• 1.375 to 20.0” diameter; 2.10 to 8.38” length
• Bore sizes from 0.625 to 5.5”
• Static torque from 0.08 to 4330 lb-ft
• Starting torque from 0.04 to 2150 lb-ft
• 24/90/110VDC coil voltage
• Operates both dry and in oil
• Modified designs and customized assemblies available

Low-cost power-off brake that is electromagnetically released. The relatively thin profile of these brakes compared to normal spring applied brakes make them a perfect candidate for a variety of applications while providing a good torque to size ratio.

• 2.8 to 9.6” diameter; 1.4 to 6.5” length
• Bore sizes from 1.2 to 5.1”
• Static torque from 20 to 2600 lb-ft
• 1800 to 5500 RPM max speed
• Operates both dry and in oil
• Modified designs and customized assemblies available

Thinnest profile power-off brake available — provides a very short package size when the brake is mounted to the rear of a motor; and when mounted to the front, there is still room for mounting a pulley. Equipped with PWM controller to reduce heat and save energy for continuous duty applications.

• 1.02 to 3.29” diameter ; 0.47 to 0.75” length
• Bore sizes from 0.19 to 0.79”
• Static torque from 0.53 to 28.32 lb-in
• 24VDC coil voltage for 0.5 sec max; 7VDC holding voltage with PWM controller
• Modified designs and customized assemblies available

This low-cost manual release power-off brake is designed to operate dry and easily mounts to a motor or frame. The brake includes a manual release lever which provides an override in the absence of power as well and a dust cover to help keep the friction surface free of debris. A torque adjustment collar also allows the torque to be manually adjusted based on the application.
