Heavy-duty industrial cylinder engineered for high-moment applications requiring precise stroke adjustment and extreme durability. Features hardened steel construction with triple chrome plating on the piston rod for corrosion resistance. The reinforced mounting structure withstands 20% higher side loads compared to standard cylinders. Requires 40μm filtered air with optional auto-switch lubrication units for continuous operation.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Foundry mold clamping mechanisms
- Heavy conveyor gate actuators
- Shipbuilding plate bending machines
Installation protocol:
Ensure parallel alignment within 0.2mm/m tolerance. Use grade 8.8 or higher mounting bolts torqued to 220-240 N·m.
Requires weekly inspection of cushion adjustment locks under vibration-heavy conditions.
