The SI40X125SCA features a double-acting design with corrosion-resistant construction, optimized for high-cycle automation systems. Its precision-machined barrel ensures ≤0.5μm surface roughness for smooth operation. The magnetic piston (built-in magnet for sensor compatibility) and adjustable cushioning prevent impact damage at stroke ends. Requires ISO 8573-1:2010 Class 3 compressed air.
- CNC machine tool clamping mechanisms
- Automated assembly line positioning
- Packaging machinery actuation
- Plastic injection molding ejectors
- Material handling transfer systems
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil if using non-lubricated air.
Maintain 0.3-1mm clearance between magnetic sensor and cylinder body.
Avoid side loads exceeding 30N during operation.
