HSH 1 SG

The output shaft of the HSH swivel motors has radial and axial hydrostatic bearings. Here, radially and axially arranged bearing pockets are supplied with pressurized oil via a separate pressure connection. As a result, the output shaft is centered radially and axially between liquid cushions and all metallic contact surfaces are permanently separated from each other by a thin liquid film. This eliminates wear caused by metallic friction in any operating state, even at zero speed compared to hydrodynamic plain bearings. In conjunction with highly dynamic control valves and angle of rotation sensors, these actuators are preferably used in controlled systems in which disturbance variables such as friction and the stick-slip effect must be reduced to a minimum. Furthermore, due to the lack of internal seals, they are ideal for test series with large numbers of load cycles where an interruption, e.g. due to the replacement of internal seals, is not permitted.
