The spring-loaded SL brakes are designed for all applications where a fail-safe brake is required. The brake consists of a hydraulic assembly, a plate assembly and a driven hub can be supplied upon request.

The SL brake is a hydro-mechanical device that is Spring Loaded and hydraulically released. A spring load exerts a compressive force between steel plates, which are mounted on the rotating shaft, and sintered plates mounted in the gear tooth ring. When oil pressure is applied, the spring load is relieved and the plates are free to move axially on the shaft hub allowing free rotation of the shaft. The brake is re-applied by releasing the oil pressure.
