Perfectly matched
for accurate rotary-linear-movements

The Eckart HSE4 rotary-linear-actuator is a combination of a rotary actuator and a dual-action linear cylinder. Consequently, with the HSE4, a rotary movement and and a linear movement can be executed in an extremely small space.

Since the rotary actuator and the linear cylinder are hydraulically driven separately, any movement sequences can be selected, such as rotaring to the left and right, linearly extending and retracting, etc. If both components are driven evenly, then both types of movement will be executed synchronously.

Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment and dimensions, the Eckart HSE4 rotary actuator can be used in a wide range of applications.

The selection and the size depends above all on the demands and the operating conditions under which the rotary-linear actuator is operating. For the planning of special items, it is also important for us to be aware of all technical details.
