About the Airtac SAI100 Standard Air Cylinder SAI100BX30S
The AirTAC SAI100X30-S is a double-acting ISO 15552 profile cylinder delivering a robust 3927 N of push force at 0.5 MPa. Its short 30 mm stroke provides rapid, high-impact clamping in confined spaces. The extruded aluminum barrel design omits tie rods, offering a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
Configured with a SUS304 stainless steel rod, this variant is built for environments where moisture or corrosive elements are present. The integrated magnet (-S) enables precise piston tracking via CMSE or DMSE sensors fitted into the dual-side barrel grooves. It features PT tapered port threads and adjustable air cushions at both ends to soften stroke impacts.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX30S Is Used
Heavy-Duty Stamping
Provides the high impact force needed for short-stroke metal forming and riveting in automated presses.
Pallet Stops
Acts as a heavy-duty stop block for large pallets on conveyor lines, absorbing kinetic energy with its cushions.
Clamp Jigs
Secures heavy workpieces inside machining centers, using the SUS304 rod to resist coolant corrosion.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX30S the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder (providing 2513 N at 0.5 MPa) lacks the necessary thrust for heavy pressing or holding. Because the 30 mm stroke is very short, side-load bending is minimal, but you should still ensure the load is axially aligned to prevent premature rod-seal wear. The adjustable end cushions must be tuned for the high kinetic energy generated at fast stroke speeds.
If your fixture loses air pressure, this standard cylinder cannot hold a load and will drift; for fail-safe holding, specify the SAIL variant with an air-released lock or use an external rod lock. This model is dimensionally interchangeable with other ISO 15552 cylinders, utilizing a G1/2 port and standard mounting accessories like FA flanges or TC trunnions.

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 SAI100BX30S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, it delivers 5497 N of push force.
Yes, the -S suffix indicates an integrated magnet, allowing CMSE or DMSE sensors to track the piston via the dual grooves on the barrel.
