Spring closed brake
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.

Features
SBR type
Ultra-thin and projection-free
Best integrated into servomotors, special small motors, robots, or FA machinery as a holding or stop brake.
Provides silent operation, free from metallic noise by eliminating metal from our disk structure.
SBM type
Easily mounted and able to withstand heavy operation
Easily mounted to general-purpose motors, abrasion resistant and dissipates heat efficiently.
Becomes a brake motor when mounted to a general-purpose motor.
SBS type Versatile and easy to use By using a multi-plate design, we are able to achieve high torque with a small diameter, making this suitable for breaking and emergency stops in many applications. Additionally, the static frictional torque can be varied by changing the number of disks.
