Clutches and Brakes

Spring Closed Type

The best choice for holding/emergency applications.

Our non-excitation (negative actuation) spring close electromagnetic brakes use a reliable multi-spring mechanism to apply braking force after power is cut off. The design of this redundant system offers very high reliability, making it ideally suited for as a holding brake or emergency stop brake.
The 3 standard series are: SBR, which is best suited to use in servomotors or robotics applications due to its ultra-thin, projection-free design, SBM, best used as an easily-mounted general-purpose motor, and SBS, which is versatile enough to suit every application.
