About the Airtac SAI100 Standard Air Cylinder SAI100BX950S
The AirTAC SAI100X950-S is a double-acting ISO 15552 profile cylinder built for demanding linear motion tasks. It generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavy material handling over its 950 mm travel distance. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that integrates easily into modern machinery.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It also features a built-in magnet (-S) that enables direct mounting of CMSE or DMSE series solid-state sensor switches along the dual grooves on the barrel. Fluid and port connections utilize a PT tapered G1/2 thread.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX950S Is Used
Long-Stroke Material Transfer
Ideal for pushing heavy pallets or workpieces across a 950 mm gap on a production line, utilizing the 3927 N thrust at 0.5 MPa to overcome friction and inertia.
Heavy-Duty Lift Gates
Provides the robust lifting force required for automated safety doors or heavy lifting platforms, with SUS304 rod material resisting moisture in industrial washdown zones.
Automated Assembly Press
Delivers consistent downward clamping pressure for component seating, while the -S magnet allows CMSE sensors to confirm exact stroke endpoints for cycle logic.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX950S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant upgrades your thrust from 2513 N to 3927 N at 0.5 MPa, stepping up to 5497 N at 0.7 MPa. If your application requires less force, dropping to the 80 mm bore saves space and air consumption. Because this model features a 950 mm stroke, managing side load is critical; long unsupported rods are prone to bending under lateral stress. We recommend pairing this cylinder with an external linear guide rail or using a dedicated guided cylinder to prevent rod-bearing wear and premature seal failure.
As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard ISO 15552 cylinder with matching 100 mm bore, 950 mm stroke, G1/2 port, and standard mounting accessories like FA/FB flanges or TC trunnions. Note that the adjustable air cushions at both ends decelerate the piston but do not lock the rod; if pressure drops, the load will drift. For position holding without live air pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.

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 SAI100BX950S 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 SAI100X950-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders that share the same 100 mm bore, 950 mm stroke, and G1/2 port configuration.
