MBRP Metric Series Power-off Spring-Set Brakes

MBRP (Power-off)

The MBRP Series are a power-off, DC spring set metric brake that provides a low-cost, multi-functional brake alternative for many applications. A simple, square drive hub attaches to the shaft with a set screw and keyway and includes an anti-rattle feature for quiet operation. The series offers a superior torque to size ratio and is engineered with friction material on the rotor assembly to boost maximum brake performance and extend life. Fully potted coils meet minimum requirements for class “F” insulation.
