High-precision adjustable cylinder featuring micro-stroke calibration via hex wrench (included). The dual cushion adjustment allows smooth deceleration control, while the chrome-carburized piston rod enhances wear resistance. Includes anti-rotation guide for stable linear motion. Requires 40μm filtered air with 1-10mg/m³ lubrication oil content (ISO VG32 recommended).
- Precision clamping fixtures in CNC machining centers
- Variable height positioning in automated assembly lines
- Packaging machine pusher mechanisms with adjustable force
- Plastic injection molding ejector systems
- Semiconductor handling equipment requiring micro-adjustments
Adjustment procedure:
Loosen lock nut → Rotate stroke adjuster (0.5mm per full turn) → Tighten nut while holding adjuster.
Perform adjustments under 0.3MPa air pressure for optimal accuracy.
Critical notes:
Avoid side loads exceeding 30N. Maximum permissible lateral play: ±0.5mm.
Re-lubricate every 500km of cumulative travel distance.
