About the Airtac SAI100 Standard Air Cylinder SAI100BX75S
The AirTAC SAI100X75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N at 0.5 MPa, making it well-suited for short-stroke clamping and high-load pressing tasks. The integrated magnet enables precise position tracking.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically exposed environments. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to absorb impact energy. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward CMSE or DMSE switch mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX75S Is Used
Heavy-Duty Stamping
Applies the 3927 N push force at 0.5 MPa to form, stamp, or rivet metal components securely in automated fabrication lines.
Pallet Clamping
Holds heavy pallets or large workpieces firmly in place during machining or packaging operations using its robust 100mm bore output.
Press Fit Assembly
Drives bearings or bushings into housings with precise 75mm travel, relying on the SUS304 rod for durability in demanding industrial settings.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX75S the Right Cylinder?
Select this 100mm bore actuator when a 63mm bore (offering 1559 N at 0.5 MPa) cannot generate the necessary thrust for your heavy fixtures. The 75mm stroke is optimal for compact, high-force movements. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for offset loads.
If your machinery requires the piston to maintain its position after a pneumatic pressure loss, note that the standard SAI air cushion only decelerates the rod at stroke end and does not lock it. For fail-safe holding, consider the SAIL variant or an external pilot-operated check valve. This model serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder with a 100mm bore, 75mm stroke, PT G1/2 ports, and a magnet.
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 SAI100BX75S FAQ
At a standard operating pressure of 0.5 MPa, this 100mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X75-S is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, allowing it to serve as a drop-in replacement using standard mounting accessories.
