About the Airtac SAI100 Standard Air Cylinder SAI100AX35S
The AirTAC SAI100X35-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke operations. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it ideal for heavy pressing and clamping duties within a compact 35 mm stroke. The extruded aluminum barrel design ensures rigid performance without the need for external tie rods.
This specific configuration includes a magnet for position sensing (-S) and features an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The dual sensor grooves on the barrel seamlessly integrate with CMSE and DMSE switches. Ports are cut with PT tapered threads, and the cylinder includes adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX35S Is Used
Heavy Duty Stamping
Provides the 3927 N push force required to seat bearings or form heavy metal components in confined spaces.
Pallet Halting
Acts as a high-strength stopper block for heavy pallets on assembly lines, utilizing the magnetic piston for timing confirmation.
Industrial Clamping
Secures large welded frames during machining operations, taking advantage of the SUS420J2 rod's durability against harsh coolants.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX35S the Right Cylinder?
Selecting this 100 mm bore model is optimal when your application demands substantial thrust within a tight linear footprint. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, which may prevent unnecessary air consumption. Conversely, if your operation requires over 6000 N, the 125 mm bore offers 6136 N at the same pressure.
Because this is a short-stroke actuator, side-load stress on the rod bearing is minimal compared to longer strokes. However, this standard SAI cylinder will drift if air pressure is lost or the valve is centered; it cannot hold a load in a power-off state. For critical drop-prevention safety, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a genuine ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 35 mm stroke, G1/2 ported actuator with matching mounting accessories like FA flanges or TC trunnions.
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 SAI100 Standard Air Cylinder SAI100AX35S FAQ
At 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If you operate at 0.7 MPa, the push force increases to 5497 N.
Yes. The SAI100X35-S is built to the ISO 15552 standard, meaning its mounting dimensions, 100 mm bore, 35 mm stroke, and G1/2 port are fully interchangeable with other ISO 15552 profile cylinders of the same size.
