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. Specific torque [Nm/bar]:32,80 Operating pressure [bar]:280 Nominal torque [Nm]:9184 Swivelling angle [ degrees° ]:120

The use of servo-hydraulic controls can significantly extend the range of applications for swivel motors. Larger loads can be slewed in a shorter time than is possible with purely hydraulic systems, where the damping travel is fixed. In conjunction with such a control system, the acceleration and braking behavior of the swivel motors can be specifically adapted to the requirements. This means that even fast and very precise movements with large masses can be safely mastered. We offer customized solutions for a wide range of applications. Our qualified team will be happy to advise you on design and realization.

The L-10 series has our smallest and most compact hydraulic drive with helical gearing. With its extremely high axial load capacity in a slim, cylindrical design with flange mounting and drive, the ultra-compact L-10 series is ideal for applications with limited space. Helac’s sliding spline hydraulic technology with helical gearing is not self-locking and offers both high impact resistance and high holding torque for demanding applications. The L-10 series functions as a rotating device as well as a mounting bracket and support structure, so that no external bearing systems, brakes or locking devices are required. Available in five standard sizes with an output torque of up to 2,825 Nm at 210 bar. Operating pressure [bar]:207 Nominal torque [Nm]:1695 Holding torque [Nm]:5650 Swivelling angle [ degrees° ]:180 Momentkapazitat [Nm]:9040

The swivel motors with attached hydraulically released spring-applied multi-disc brake are recommended if a swivel position must remain unchanged once it has been reached – even over an unlimited period of time – despite the effect of a load torque. The brake is used solely to hold the load. It should only be noted that large transmission delays in the lines can cause time differences between the switching off of the swivel motor and the application of the released brake caused by spring force. In order to provide our customers with the right drive for all areas of application, the HSB swivel motor is available in a total of 5 different versions. We have listed the most important data below. You can find all further details in our data sheet.
