Precision-engineered adjustable stroke cylinder featuring micro-positioning capability (±0.5mm repeatability). The integrated dual-cushion system minimizes end-impact noise while maintaining 98% energy efficiency. Corrosion-resistant construction with IP54-rated seals enables reliable operation in humid environments. Requires filtered air (5-50μm) with ISO 8573-1:2010 Class 3.2.4 purity standards.
- Precision clamping fixtures in CNC machining centers
- Variable height positioning in conveyor systems
- Packaging machine flap adjustment mechanisms
- Semiconductor wafer handling equipment
- Automated paint spray distance control
Installation note:
Always degrease mounting surfaces with isopropyl alcohol before assembly.
For stroke adjustment: 1) Loosen lock nut 2) Rotate adjustment screw (0.25mm per full turn)
3) Retighten while maintaining 0.5-0.8Nm torque. Perform adjustments at 0.2MPa or lower.
