About the Airtac SAI100 Standard Air Cylinder SAI100AX55
The AirTAC SAI100X55 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N at 0.5 MPa, making it well-suited for short, high-impact clamping and lifting tasks. The 55 mm stroke ensures rapid actuation in compact machinery layouts.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid compatibility is limited to 40 um filtered air, operating reliably between -20 and +70 C. Because this variant lacks the -S magnet option, position sensing must be achieved externally rather than using the barrel's integrated sensor grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX55 Is Used
Heavy-Duty Clamping
Generates 3927 N of push force at 0.5 MPa to secure thick steel plates during machining or welding operations.
Stamping Press Feed
Uses the short 55 mm stroke to rapidly push and position heavy metal blanks into forming dies.
Pallet Lift Stations
Provides the raw lifting power needed to elevate loaded pallets at the initial stage of a conveyor transfer.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX55 the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (delivering 1559 N at 0.5 MPa) is insufficient for moving heavy payloads. The 55 mm stroke is optimal for brief, powerful movements. If your mechanism must maintain its position during a pressure loss or valve centering, the standard SAI will drift; you should specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder instead.
Mounting is highly versatile via the ISO 15552 interface, accepting FA/FB flanges, LB foot brackets, or TC trunnion styles. The PT tapered port thread guarantees a tight pneumatic connection. For any future application requiring longer strokes, ensure external guides are used to prevent rod-bearing bending from side loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
