Precision stroke-adjustable pneumatic cylinder featuring dual cushioning control via external screw adjusters. The hexagonal barrel design enables wrench adjustments during operation. Includes anti-rotation keyway and corrosion-resistant hard chrome plated rod (3-5μm thickness). Requires 40μm filtered air with max 1mg/m³ oil content.
- Precision positioning in semiconductor handling robots
- Variable clamping force fixtures for CNC machining
- Adjustable press mechanisms in PCB assembly
- Material feed systems with stroke compensation
- Automotive assembly line tooling adjustments
Adjustment procedure:
Loosen locknut → Turn cushion screw (CW to shorten stroke, CCW to extend) →
Test cycle 3-5 times → Retighten locknut to 1.2-1.5N·m torque.
Always depressurize before adjustments.
