A space-saving linear actuator with precision-machined square profile, featuring dual anti-rotation design for stable vertical/horizontal mounting. The chrome-plated piston rod resists corrosion in humid environments. Requires 40μm filtered air and ISO VG32 hydraulic oil lubrication (optional).
- PCB board clamping in SMT machines
- Precision paper feeding in POS printers
- Micro-part positioning in watch assembly
- Lens adjustment mechanisms in optical equipment
- Valve actuation in portable medical devices
Installation tip:
Maintain 0.5mm minimum clearance between rod end and workpiece.
For vertical mounting, orient spring-side port downward to prevent
moisture accumulation. Lubricate every 500,000 cycles.
