The T20 series with toothed output shafts and a rotation angle of 200-220 degrees is ideal for applications where torque generation and higher cycle rates are the most important requirements. Helac’s sliding spline technology with helical teeth is not self-locking and offers both high impact resistance and a high holding torque for demanding applications. It functions both as a rotating device and as a mounting bracket and support structure, so that no external bearing systems, brakes or locking devices are required. Available in three standard sizes with an output torque of up to 6,780 Nm at 210 bar. Operating pressure [bar]:207 Nominal torque [Nm]:5085 Holding torque [Nm]:10622 Swivelling angle [ degrees° ]:220 Momentkapazitat - Spreizmoment [Nm]:7628

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.
