High-performance industrial cylinder designed for heavy-duty applications requiring precise linear motion. Features dual adjustable pneumatic cushions for smooth deceleration and impact reduction at stroke ends. The corrosion-resistant construction ensures reliable operation in harsh environments. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Material handling systems (conveyor diverters, lift mechanisms)
- Packaging machinery (case erectors, palletizers)
- Automotive assembly line fixtures
- Plastic injection molding ejectors
- Paper processing equipment
Installation guidelines:
Allow minimum 10mm clearance around cylinder body for heat dissipation.
Use flexible couplings for stroke >500mm applications. Lubricate through
air supply (ISO VG32 turbine oil recommended). Adjust cushion screws
incrementally (1/4 turns) during commissioning.
