Heavy-duty industrial cylinder featuring wear-resistant steel construction and precision-ground piston rod. The dual adjustable cushioning system minimizes impact noise while allowing precise stroke-end positioning. Chrome-plated inner tube surface reduces friction loss by 18% compared to standard cylinders. Requires ISO VG32 hydraulic oil or equivalent for lubrication.
- Press machine ejection systems
- Automotive welding fixture positioning
- Construction equipment boom control
- Large-scale packaging line actuators
- Plastic injection molding machine core pulls
 Installation notes:
 Installation notes:1. Use M12×1.75 grade 8.8 mounting bolts (min. 30mm engagement)
2. Maintain 0.5–1mm alignment tolerance during flange mounting
3. Lubricate through air inlet port before initial operation
4. Cushion adjustment: Turn clockwise to increase damping force (max. 2.5 rotations)
