Precision-engineered adjustable stroke cylinder featuring dual-position mechanical locks for mid-stroke stopping capability. The chrome-plated piston rod and anodized aluminum body ensure corrosion resistance in humid environments. Integrated shock absorbers allow fine-tuning of end-position damping. Requires ISO 8573-1 class 3 lubricated air (40μm filtration).
- Variable-height positioning in automated assembly lines
- Press tooling with depth adjustment requirements
- Material handling systems needing stroke customization
- Packaging machinery with product size variations
- Automotive fixture positioning devices
Installation note:
Adjustable stoppers require periodic lubrication (use ISO VG32 hydraulic oil).
Maintain minimum 0.5mm clearance between stopper and cylinder body during adjustment.
Maximum side load must not exceed 10% of axial thrust capacity.
