The SI63X350 industrial cylinder combines high thrust force (1,960N @6bar) with extended stroke precision, featuring dual adjustable air cushions for smooth deceleration. Its hard-anodized barrel resists abrasive wear in dusty environments, while the triple-lip rod seal prevents contamination ingress. Requires 40μm filtered air and optional magnetic piston for position sensing.
- Press machine ejection systems
- Automotive welding fixture clamping
- Bulk material gate valve actuation
- Plastic injection molding machine core pulls
- Heavy-duty conveyor diverters
Installation note:
Mounting axis alignment tolerance ≤0.2mm/m. For vertical installations,
use rod-down orientation to prevent condensate accumulation.
Allow 20mm clearance behind cushion screws for adjustment.
