The SI125X290 industrial cylinder delivers 15,600N maximum thrust at 0.8MPa, featuring triple sealing (piston, rod, end cover) for leak-proof operation. Its hard-anodized barrel resists abrasive particles, while the chrome-plated piston rod withstands side loads. Requires ISO 8573-1:2010 Class 3-4-3 compressed air and periodic lubrication (ISO VG32 equivalent oil).
- Metal stamping press ejection systems
- Plastic injection molding machine clamp units
- Automotive assembly line positioning fixtures
- Heavy-duty material handling gates
- Paper mill roller engagement mechanisms
Installation note:
For vertical mounting, install a mechanical lock nut on the piston rod.
Maintain 0.5-1mm alignment tolerance during mounting. Lubricate every
2,000km of cumulative stroke movement or 6 months (whichever comes first).
