High-precision industrial cylinder featuring a dual-channel adjustable stroke system with mechanical locking. The hardened piston rod (Cr-Mo steel) and multi-lip seal design ensure ≤0.5mm air leakage per minute at 0.5MPa. Includes anti-rotation guide for vertical applications.
Industrial Applications:
- Die-casting machine ejection systems requiring variable stroke control
- Press tool height adjustment in automotive manufacturing
- Palletizing robot end-effector positioning
- Glass tempering furnace door actuators
- Paper roll tensioning mechanisms

Cycle Life:
5,000km travel distance or 5 million cycles (whichever comes first)
before seal replacement recommended. Compatible with Class 4
filtration (0.01mm filter).
