The SI40X858S features a unique "X-series" reinforced structure with 30% higher side load capacity than standard models. Its chrome-silicon alloy piston rod resists bending deformation under full extension. The cylinder incorporates a dual-seal labyrinth design that reduces particulate contamination by 72%, making it ideal for cleanroom applications.
- Automated palletizing systems (food/beverage sector)
- Plastic injection molding machine ejectors
- Automotive welding fixture positioning
- Paper converting equipment tension control
- Solar panel laminator compression mechanisms
Installation protocol:
Requires perpendicular alignment within 0.2mm/m tolerance. Use flexible couplings for stroke >500mm.
For vertical mounting, install speed controller at lower port. Lubricate with ISO VG32 pneumatic oil.
Critical note:
Avoid rapid cycling (>80% duty cycle) beyond 700mm stroke. Install intermediate support when stroke/rod diameter ratio exceeds 50:1.
