About the Airtac SAI100 Standard Air Cylinder SAI100AX250S
The AirTAC SAI100X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for high-inertia pressing and lifting tasks over a 250 mm stroke. The extruded aluminum barrel design omits traditional tie-rods, offering a clean exterior that resists debris accumulation.
This specific configuration includes a SUS420J2 stainless steel rod for superior corrosion resistance in humid or washdown environments. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE or DMSE reed switches along the dual sensor grooves molded into the barrel profile. It also features adjustable air cushions at both ends to absorb impact energy and PT tapered port threads for a reliable, sealed connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX250S Is Used
Heavy-Duty Stamping
Provides the necessary 5497 N of thrust at 0.7 MPa to actuate mechanical stamping and forming presses securely over a 250 mm travel distance.
Pallet Diversion
Ideal for heavy material handling systems, using the robust 100 mm bore to push loaded pallets laterally across high-throughput conveyor networks.
Automated Clamping
Secures large metal or composite workpieces during CNC machining or welding operations, utilizing the full stroke to accommodate varying part sizes.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX250S the Right Cylinder?
Selecting this 100 mm bore cylinder is ideal when an application demands upward of 3927 N of thrust at 0.5 MPa, stepping up significantly from the 63 mm bore class which yields 1559 N. If your system operates at 0.7 MPa, expect the output to climb to 5497 N. For operations requiring less force, dropping down to an 80 mm bore provides 2513 N while saving valuable mounting space.
With a 250 mm stroke, it is crucial to manage potential side loads to prevent rod-bearing bending and premature wear. Utilizing an external guide rail or a dedicated guided cylinder ensures smooth linear motion and protects the piston rod from lateral forces. Remember that the standard adjustable air cushions only decelerate the piston near the stroke ends; they do not hold a load. If the pneumatic supply is lost, the rod will drift, so incorporate a SAIL pneumatic lock or an external pilot-operated check valve for fail-safe position holding. This model is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders of the same bore and stroke, utilizing standard FA/FB flanges or TC trunnion mounts.

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 SAI100AX250S FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. If the pressure is increased to 0.7 MPa, the push force rises to 5497 N.
