The SI40AX195 features precision honed tubing and dual anti-rotation guides for smooth linear motion. Its wear-resistant design incorporates a magnetic piston (DMR-44H grade) for position sensing compatibility. The cylinder operates effectively in high-cycle applications with 1.5 million guaranteed cycles at 0.5MPa.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool part positioning
- Packaging equipment vertical lift systems
- Automotive welding fixture actuators
Installation guidelines:
Use M5 class 8.8 mounting screws torqued to 4.5N·m.
Maintain 0.5mm minimum alignment tolerance between rod and load.
Lubricate with ISO VG32 hydraulic oil for initial operation.
Critical note:
Avoid side load exceeding 15N·m. Maximum permissible rod end play: ±1.2°.
Use AIR TAC UC-1 grease for high-frequency applications (>2Hz).
