High-force industrial cylinder with extended stroke capability, featuring precision-machined aluminum construction and dual adjustable cushions for smooth end-of-stroke deceleration. The SI63X850S utilizes a chromium-plated piston rod with triple sealing system (wiper seal, main seal, and rod guide) for enhanced durability in dusty environments. Requires 40μm filtered lubricated air (ISO 8573-1 class 4) for optimal performance.
- Automated palletizing systems in logistics centers
- Press machine ejection mechanisms
- Large-scale woodworking equipment actuators
- Automotive assembly line clamping devices
- Plastic injection molding machine core-pulling units
Installation note:
When mounting horizontally, support the cylinder at mid-span every 1.5m stroke length.
For vertical installations exceeding 500mm stroke, use counterbalance valves.
Lubricate through air supply (ISO VG32 recommended) if non-lubricated operation is required.
