Features & Benefits
Modular design
The HA series adopts a modular design with strong versatility. Different combinations of action modes, strokes, spring ranges, and handwheels can be achieved with only minor changes. Its replaceability and storability help shorten the supply cycle.
High-strength, compact design
The housing is punched from quality steel plate, offering light weight and high strength. Multiple springs are used internally for a compact structure, small volume, and refined appearance.
High-performance grease:
Imported lubricating grease is used to ensure long-term, stable lubrication of the guiding part. It features good thermal stability, resistance to melting, low volatility, resistance to chemical corrosion and moisture, no reaction with rubber, and good oxidation and aging resistance.
Good corrosion resistance
The housing and yoke undergo powder coating, and the rod is made of stainless steel, with a standard corrosion protection grade of C3 or above. A special surface painting process is also used to meet C5 or above corrosion protection grades, accommodating different environmental corrosion requirements.
Maintenance-free operation
Each HA actuator can deliver long-term, efficient operation without maintenance.
