1. Understanding Hydraulic Rotary Actuator Specifications

Before diving into selection criteria, familiarize yourself with key actuator specifications:

1.1 Torque Output

· The rotational force the actuator can deliver, measured in Newton-meters (Nm) or pound-feet (lb-ft).

· Ensure the actuator provides sufficient torque for the load requirements.

1.2 Angle of Rotation

· Specifies the actuator’s range of motion, typically 90°, 180°, or 360°.

· Match the rotation angle to the system’s functional needs.

1.3 Pressure Range

· Indicates the operating pressure limits, typically measured in bar or psi.

· Choose an actuator that aligns with your system’s hydraulic pressure specifications.

1.4 Mounting Options

· Includes flange, trunnion, or foot-mounted designs.

· Select a mounting style compatible with your application setup.

1.5 Size and Weight

· Actuators come in various sizes and weights to suit space-constrained or heavy-duty systems.

· Ensure compatibility with your system’s spatial and weight limitations.
