The spring loaded SL brakes are designed for all applications where a fail safe brake is required.
The brake consists of an hydraulic assembly, a plate assembly and a driven hub which can be supplied by TRANSFLUID upon request. The SL series is a hydro-mechanical device which is Spring Loaded and hydraulically released.
A spring load exerts a compressive force between steel plates, which are mounted on the rotating shaft, 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 dumping the oil pressure
