About the Airtac SAI100 Standard Air Cylinder SAI100BX750S
The AirTAC SAI100X750-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 and a pull force of 3681 N, making it well-suited for moving substantial loads over its 750 mm stroke. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It is built with a -S magnet for direct integration with CMSE and DMSE sensor switches, which seat neatly into the dual grooves on the barrel. The cylinder operates at speeds from 30-800 mm/s and uses adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX750S Is Used
Pallet Transfer
Pushes heavy loaded pallets 750 mm between conveyor lanes, utilizing the 3927 N push force to overcome friction and inertia smoothly.
Press Ejection
Ejects formed metal or plastic parts from large press beds, relying on the SUS304 rod to withstand occasional coolant spray.
Vertical Lift Gate
Actuates a 750 mm lifting gate for material routing, using the integrated -S magnet and DMSE switches to confirm end positions.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX750S the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm bore falls short—the 80 mm yields 2513 N at 0.5 MPa, whereas this 100 mm provides 3927 N, giving you the extra thrust needed for high-friction or heavy-mass tooling. For a 750 mm stroke, side load is a primary concern; long unsupported rods are prone to bending under lateral stress. To prevent premature rod-bearing wear, pair this cylinder with an external linear guide or utilize a guided cylinder carriage.
Because it is a standard double-acting cylinder, it will not maintain its position if air pressure drops or the valve is centered. If your application requires the load to be held securely without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model uses PT G1/2 ports and is dimensionally interchangeable with other ISO 15552 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 SAI100 Standard Air Cylinder SAI100BX750S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X750-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are interchangeable with other ISO 15552 cylinders of the same bore size. You can drop it into existing foot, flange, or trunnion mounts.
