A heavy-duty industrial cylinder engineered for long-stroke applications requiring consistent force output. Features chrome-plated piston rod with integrated scrapers for contamination resistance. The double-sealed piston design minimizes internal leakage, while magnetic versions (optional) enable position sensing. Requires 40μm filtered lubricated air.
- Automotive assembly line clamping fixtures
- Steel plate stamping machinery
- Injection molding machine ejectors
- Warehouse automated lifting platforms
- Paper processing equipment actuators
Installation note:
Ensure proper alignment using alignment couplers for strokes over 500mm.
Apply anti-vibration pads when mounting on thin steel plates.
Lubricate through air port for first 1,000 cycles (use ISO VG32 turbine oil).
