Rotary hydrostatic bearing actuators
Servotest manufactures two types of rotary hydrostatic bearing actuators; dual-vane & 'push-push' torque. Selection of the appropriate actuator type is application dependent. Typical operating lives are in excess of 5 x 109 cycles.
Nominally rated for operation at 210 bar supply pressure, Servotest actuators can also work with pressures of up to 280 bar. Modular in design, they provide many options on stroke, force, flow capacity and accessories for a wide range of dynamic and static test applications.
