High-precision long-stroke cylinder featuring wear-resistant chromium plating and precision honed tube. The SI40X1295S combines heavy-duty construction with smooth operation, utilizing a dual-seal design (wiper seal + main seal) for enhanced contamination resistance. Includes built-in magnet for sensor mounting and optional auto switch kits.
- Automated material handling systems
- Plastic injection molding machine ejectors
- Textile machinery tension control
- Automotive assembly line positioning
- Packaging machine vertical lift mechanisms
Installation note:
Requires guided mounting for strokes over 500mm. Use rigid mounting brackets at both ends for long-stroke applications. Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa. Avoid side loads exceeding 30N.
