The SI80X850S heavy-duty cylinder combines extended stroke capability with exceptional lateral load resistance through its integrated guide rail design. Featuring dual-sensor slots for magnetic switch compatibility (SM/SD series), this model delivers 2,512N thrust at 0.5MPa with <2mm/s creep speed. The triple-seal construction prevents internal bypass leakage even under low-lubrication conditions.
- Automotive press line material handling
- Foundry machine ejection systems
- Plastic injection molding clamp units
- Steel coil transfer systems
- Shipbuilding plate bending machinery
Installation guidelines:
Use M12×1.25 mounting bolts (grade 8.8 or higher) with anti-vibration washers.
Maintain 0.5-1mm/kg alignment tolerance for every 100kg payload. Lubricate through
AUX1/8 oil port weekly in high-cycle applications (>500,000 cycles/month).
