About the Airtac SAI40 Standard Air Cylinder SAI40AX35
The AirTAC SAI40X35 is a double-acting ISO 15552 profile cylinder engineered for short-stroke automation. It provides a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it well-suited for compact routing and clamping jobs. The 35 mm stroke allows for rapid cycling without occupying excessive machine footprint.
This genuine unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of reed switches. Customers can specify PT tapered port threads for this specific configuration.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX35 Is Used
Compact Part Clamping
Ideal for securing small machined components during secondary milling or drilling operations using its 628 N push force.
Package Diverting
Executes short, rapid strokes to push lightweight cartons or totes from a main conveyor line onto a secondary spur.
Gate Control
Actuates small process flow gates or pneumatic flaps in light-duty material handling systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX35 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks the necessary thrust, but a 50 mm bore (982 N) would be physically oversized. The 35 mm stroke is optimal for short linear actuation, minimizing rod overhang and side-load stress on the front bearing.
Because it is a double-acting cylinder, the SAI40X35 relies on continuous air pressure to hold its position. If your fixture loses air, the piston will drift; for fail-safe load holding, consider the SAIL variant with an air-released lock or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it offers a direct replacement footprint matching other industry-standard 40 mm bore cylinders.
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.
Airtac SAI40 Standard Air Cylinder SAI40AX35 FAQ
At an operating pressure of 0.5 MPa, the SAI40X35 generates a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X35 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface and 40 mm bore dimensions as other compliant cylinders, allowing for a seamless direct replacement.
