A heavy-duty industrial cylinder designed for high-load linear motion applications. Features precision-machined components with anodized surfaces for corrosion resistance. The STC variant includes integrated cushioning adjustment screws and reinforced rod bearings for shock absorption. Compatible with magnetic sensors (sensor slots pre-machined). Requires filtered air with 40μm filtration (ISO 8573-1 class 4).
- Automotive assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- Steel plate pressing/stamping systems
- Palletizing robot end-effector actuators
- Paper mill roller positioning systems
Installation note:
Maintain 0.05mm/m alignment tolerance during mounting. Use flexible couplings
for stroke lengths exceeding 100mm. For vertical installations, implement
counterbalance valves. Lubricate every 3,000km of cumulative travel.
Lifespan: 5,000km (under S1 duty cycle)
Repeat accuracy: ±0.2mm (with proper guidance)
Air consumption: 1.57L/stroke @ 0.5MPa
