Heavy-duty industrial cylinder with precision-ground steel construction, designed for high moment load applications. Features dual adjustable cushioning with 20° rotation-adjustable buffers to prevent piston impact. The hardened piston rod incorporates a multi-layered seal system (NBR+PTFE) for ≤0.5cm³/min air leakage. Requires 5μm filtered air with lubrication (ISO VG32 recommended).
- Press machine ejection systems
- Automotive welding fixture positioning
- Die casting machine core pulling mechanisms
- Heavy conveyor gate actuation
- Paper processing equipment clamping
Installation note:
Ensure proper alignment within 0.2mm/m using laser alignment tools.
Apply anti-seize compound (copper-based) on mounting threads.
Allow 25mm clearance behind cushion adjustment screws for maintenance access.
