A heavy-duty ISO cylinder with precision-machined guide bands for minimal friction, featuring dual adjustable cushioning and corrosion-resistant construction. The SI80X250H delivers consistent thrust force in harsh environments, with wear-resistant rod seals rated for 3,000km+ service life under standard conditions. Requires filtered air (5-50μm) with max particle concentration ≤5mg/m³.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Packaging machine clamping mechanisms
- Foundry equipment material handling
- Plastic injection molding machine core pulls
Installation notes:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use rod-end support brackets (optional accessory ASI80-SB). Lubricate through air supply at 1-2 drops/m³
for optimal seal performance.
