A heavy-duty long-stroke cylinder designed for high-momentum applications requiring precise linear motion. Features dual adjustable cushioning for smooth deceleration and reduced impact noise. The triple-seal design (rod seal, buffer seal, and wiper) ensures exceptional durability in contaminated environments. Includes ISO 6432 mounting interfaces for flexible installation.
- Automotive assembly line clamping mechanisms
- Injection molding machine ejector systems
- Steel coil handling equipment
- Large-format CNC router Z-axis control
- Warehouse automated stacking systems
Installation note:
Requires rigid mounting structure due to extended stroke length. Maintain 0.5° maximum angular misalignment during installation. Use supported mid-stroke brackets for strokes over 500mm to prevent rod deflection. Lubricate rod weekly in high-cycle applications (>500k cycles/year).
