About the Airtac SAI100 Standard Air Cylinder SAI100BX180
The AirTAC SAI100X180 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa. This 100 mm bore and 180 mm stroke configuration is ideal for heavy-duty automation requiring substantial thrust. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific unit is built with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in demanding environments. It features PT (tapered) G1/2 ports and uses adjustable air cushions at both ends to manage impact deceleration. For applications needing end-of-stroke confirmation, the barrel includes dual sensor grooves compatible with CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX180 Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa needed to actuate pressing and stamping dies in metal fabrication lines.
Pallet Diverting
Handles heavy pallets laterally across conveyor belts where substantial side-thrust and reliable 180 mm extension are required.
Plastic Molding Eject
Ejects dense molded plastic parts from heavy machinery, utilizing the SUS304 rod for resistance against factory moisture.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX180 the Right Cylinder?
Selecting this 100 mm bore is optimal when a 80 mm bore (providing 2513 N at 0.5 MPa) lacks sufficient thrust, but you want to avoid stepping up to a 125 mm body which requires a slower 30-500 mm/s operating speed. The 100 mm bore operates efficiently at 30-800 mm/s. Because the stroke is 180 mm, side-load risks are moderate, but ensuring proper rod bearing alignment remains critical to prevent premature seal wear.
As a standard double-acting cylinder, the SAI100X180 relies on live air pressure to maintain position; if air is lost or exhausted, the piston will drift. Do not rely on the adjustable air cushion to hold a load—it only decelerates the piston near the stroke end. For positive holding without continuous pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To replace an existing unit, match the 100 mm bore, 180 mm stroke, G1/2 port, and your required mounting accessory (such as FA flange or TC trunnion).

- ✓ 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 SAI100BX180 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X180 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement by matching the 100 mm bore, 180 mm stroke, and G1/2 port interface.
