About the Airtac SAI100 Standard Air Cylinder SAI100X250S
The AirTAC SAI100X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N push force at 0.5 MPa, this 100mm bore unit effortlessly drives demanding loads. The 250mm stroke provides ample extension for indexing, clamping, and press operations. Its extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that drops directly into existing ISO 15552 mounting footprints.
This specific configuration includes a piston magnet for position detection. It works seamlessly with CMSE and DMSE series reed switches, which seat neatly into the sensor grooves machined on both sides of the barrel. The standard carbon steel piston rod offers high tensile strength for industrial environments, while adjustable air cushions at both ends absorb end-of-stroke kinetic energy to reduce shock.

Where the Airtac SAI100 Standard Air Cylinder SAI100X250S Is Used
Heavy-Duty Stamping
Provides the 3927 N force required to press bearings, form light gauge metals, and execute rigid stamping tasks at 0.5 MPa.
Pallet Diverting
Extends 250mm to push heavy product pallets off a high-speed main conveyor line onto secondary packaging lanes.
Automotive Component Clamping
Holds heavy cast engine blocks or transmission housings securely in place during CNC machining operations.
Is the Airtac SAI100 Standard Air Cylinder SAI100X250S the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your application requires substantial thrust that smaller bores cannot provide. If 3927 N at 0.5 MPa exceeds your actual load requirements, dropping down to an 80mm bore saves air consumption and cycle time. Conversely, if you need the maximum 5497 N push force at 0.7 MPa, this model handles it effortlessly within its 0.15-1.0 MPa operating range.
Because the 250mm stroke generates significant side-load leverage on the rod bearing, external guide rails are recommended to prevent premature seal wear if the load is not perfectly axial. Note that this standard SAI variant does not hold position upon loss of air pressure; for dead-drop prevention, consider the SAIL or BSAI locking variants. Replacement mounting uses standard ISO 15552 accessories like FA flanges or TC trunnions, G1/2 PT ports, and the -S magnet option for switch readiness.

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 SAI100X250S FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If operating pressure increases to 0.7 MPa, the push force rises to 5497 N.
The SAI series is dimensionally interchangeable per ISO 15552 standards. While we do not claim it is identical to a specific brand's part, its standardized mounting dimensions, G1/2 ports, and accessory footprint allow it to serve as a direct drop-in replacement for other ISO 15552 profile cylinders.
