Built-on Brakes

Brakes are used to limit and regulate the rotational speed of the motor or can also be used as a holding brake for positioning conveyor belts, for example.

For sizes 71 to 160, we have developed our own brake that can be installed on both the Drive-end and the Non-Drive end. Outside of these sizes, we work with various well-known manufacturers to offer tailor-made solutions.
