The SI40AX65 features a space-saving design with integrated mounting grooves for flexible installation. Its hard-anodized piston rod (HRC 45-50 hardness) ensures wear resistance in high-cycle applications. The dual sealing system combines a primary U-cup seal with secondary wiper ring, achieving ≤0.5mm/s leakage rate at 0.5MPa. Includes magnetic piston for sensor compatibility.

- CNC machine tool door interlocks
- Electronics assembly pick-and-place units
- Pharmaceutical blister packaging systems
- Automated conveyor gate controls
Installation note:
Lubricate with ISO VG32 hydraulic oil before operation. Maintain 0.3-1mm clearance between magnetic sensor and cylinder body. Maximum side load capacity: 35N at mid-stroke. For vertical mounting, use spring-up orientation to prevent piston drift.
