Hydraulic Rotary Actuators – SM4

The Eckart HSE4 rotary-linear actuator is a combination of a rotary actuator and a dual-action linear cylinder, allowing for full flexibility in a minimal amount of space. Consequently, both a rotary movement and a linear movement can be executed even when operated in an extremely small area. Additionally, since the rotary actuator and the linear cylinder are hydraulically-driven separately, any movement sequences can be selected: for example, rotating to the left and right, extending linearly, and retracting. Furthermore, if both components are driven evenly, then both types of movement will be executed synchronously. The directional valve controls the movement of rod rotation and linear stroking.

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

Not only is the HSE4 a compact and robust unit, but it is also wear-resistant, efficient, and cushioning. Additionally, the HSE4 unit can be driven via “black and white” or with proportional, control, and servo valves. For the purpose of subsequent driving, the piston end-positions at the linear cylinder and at the rotary actuator can be scanned via electronic end-position acknowledgement mechanisms. Ultimately, with the HSE4, you have a high-performing product that is both robust and compact, allowing for optimal adaptation depending on your specific requirements.
