About the Airtac SAI100 Standard Air Cylinder SAI100BX40
The AirTAC SAI100X40 is a double-acting ISO 15552 profile cylinder engineered for high-force automation tasks. Delivering a robust 3927 N of push force at just 0.5 MPa, this 100mm bore actuator is built to move substantial loads. The short 40mm stroke provides rapid, end-to-end cycling without occupying excessive machine footprint.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a piston magnet. For applications requiring end-position holding without continuous air pressure, consider the SAIL or BSAI locking variants, as standard adjustable air cushions only decelerate the piston at stroke ends.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX40 Is Used
Short-Stroke Stamping
Ideal for applying high pressing or stamping forces over a compact 40mm travel distance in metal fabrication cells.
Heavy Pallet Clamping
Provides the robust 3927 N push force needed to secure heavy pallets or fixtures momentarily during machining or wrapping.
Rigid Gate Actuation
Moves heavy industrial safety gates or chutes rapidly with minimal extension length, benefiting from the durable SUS304 rod.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX40 the Right Cylinder?
Selecting the SAI100X40 is optimal when a brief, high-impact motion is required. If your application demands less than 3927 N at 0.5 MPa, stepping down to the 80mm bore yields 2513 N, saving valuable air consumption. Conversely, moving heavy fixtures requiring more force would necessitate the 125mm bore, which outputs 6133 N.
Because this is a genuine AirTAC profile cylinder, it serves as a drop-in replacement for any standard ISO 15552 mounting interface. To match this exact unit, specify a 100mm bore, 40mm stroke, PT port threads, no magnet, and pair it with standard 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 SAI100BX40 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X40 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 100mm bore, 40mm stroke, and mounting dimensions.
