HSB Rotary Actuators

with hydraulic retaining brake

Rotary actuators with mounted hydraulically ventilated spring-pressure multiple disc brake are recommended if, a pivot position attained - even for an unlimited period - is to be maintained unchanged despite the impact of a load torque. The sole purpose of the brake is to hold the burden. Care must only be taken that major transmission delays in the lines between shut-down of the rotary actuator may cause the release of the ventilated brake via spring pressure.
