The SAU40X250 medium-duty pneumatic cylinder features anodized aluminum construction with chrome-plated piston rod (5μm coating thickness). Its dual anti-rotation design ensures precise linear motion, while the built-in magnetic ring (optional) enables position feedback when paired with sensors. The cylinder operates effectively in humid environments with ≤95% RH non-condensing conditions.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool chip conveyors
- Automotive welding fixture positioning
- Food processing packaging actuators
Installation guidelines:
Align cylinder axis within ±0.2° angular misalignment tolerance.
Use flexible couplings for stroke-end force absorption. Lubricate with ISO VG32 hydraulic oil
if operating below 0.3 MPa. Allow 20mm clearance around cylinder body for heat dissipation.
