A space-saving linear actuator with precision square housing, featuring a compact pen-type design for tight installations. The chrome-plated piston rod and aluminum alloy body ensure corrosion resistance and lightweight operation (60% lighter than standard cylinders). Integrated buffer adjustment screw prevents end-impact vibration.
- PCB handling robots in electronics manufacturing
- Micro-part ejection systems
- Medical device positioning mechanisms
- Semiconductor wafer processing equipment
- Automated test fixture actuation
Installation tip:
For vertical mounting, reduce initial pressure to 0.3MPa maximum to prevent spring overload.
Use C-Lube Series 1000 pneumatic oil for maintenance. Allow 5mm clearance around cylinder body for heat dissipation.
Note:
Spring return force decreases at temperatures above 60℃. Not recommended for continuous duty cycles exceeding 80%
without auxiliary cooling. Requires 5μm filtration for optimal seal life.
