The Model I-300, a spring engaged, air released, power-off brake from Nexen Group, Inc., is designed to provide high torque for backlash-free holding and emergency stopping on indexers and positioning systems. The I-300’s high torque and short response time ensure a short stopping distance. The brake connects to the shaft with tapered, keyless locking devices. It is normally engaged until air pressure is applied to release it. Nexen’s patented braking element locks and holds the shaft in position without any displacement upon engagement or reversing of the load.
