Hydraulic Rotary Actuators

Engineered for demanding heavy-duty applications, ASHUN’s RA Series Hydraulic Rotary Actuators seamlessly integrate precision double-helix meshing technology with a zero-leakage, highly robust architecture. This design delivers superior torque output and exceptionally smooth rotational control. Ideal for construction machinery, marine environments, and advanced automation, the RA Series significantly elevates overall system efficiency, providing an industrial-grade solution you can depend on.

High Power Density & Compact Footprint

Utilizes precision double-helix spline technology to output immense torque within a minimal footprint, perfectly suiting confined installation spaces.

Integrated High-Load & Anti-Side-Load Structure

Combines powerful rotational force with exceptional structural support, capable of withstanding extreme radial loads and bending moments without requiring external bearings.

Zero Internal Leakage & Precise Position Locking

Outstanding zero-leakage sealing technology achieves accurate, drift-free load holding without the need for external mechanical brakes.

Ultra-Low Backlash for Smooth Motion Control

Delivers jerk-free, consistently uniform bidirectional rotational control, meeting the stringent demands of precise angle micro-adjustments.

High Customizability & Safety Valve Block Integration

Supports standard 180° and 360° rotation, with customizable rotation angles, shaft ends, mounting flanges, and integrated load-holding safety valves.
