About the Airtac SAI100 Standard Air Cylinder SAI100AX350S
The AirTAC SAI100X350-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force, making it well-suited for high-thrust actuation over its 350 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies the mounting of sensors and accessories.
This specific configuration includes a magnet for use with CMSE and DMSE switches, fitting neatly into the dual sensor grooves machined on both sides of the barrel. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and air is supplied via PT threaded ports. Adjustable air cushions at both ends ensure smooth deceleration of dynamic loads within the 30-800 mm/s speed range.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX350S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to actuate medium-tonnage stamping and forming presses reliably over a 350 mm working distance.
Pallet Diversion
Ideal for heavy-material handling lines, using the magnet-equipped dual grooves to trigger CMSE position switches for precise pallet routing.
Automated Assembly Presses
Drives large component seating operations where the SUS420J2 stainless steel rod offers reliable resistance to minor environmental moisture.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX350S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant yields a significant thrust upgrade, stepping up from 2513 N to 3927 N at 0.5 MPa. If an application requires less force and a smaller footprint, the 80 mm bore is the logical step down. Conversely, if your system needs to exceed 3927 N, stepping up to the 125 mm bore provides 6136 N.
Because this model features a 350 mm stroke, the extended unsupported rod is susceptible to bending under side loads, which can accelerate rod-bearing wear. For optimal longevity, guide the load externally or utilize a guided cylinder carriage to prevent lateral stress. Note that a standard SAI cylinder will drift if air pressure is lost; if your application requires true position holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, this model serves as a drop-in dimensional replacement for other ISO 15552 cylinders, matching the 100 mm bore, 350 mm stroke, 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 SAI100AX350S FAQ
At a standard 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X350-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions, 100 mm bore, 350 mm stroke, and G1/2 port are dimensionally interchangeable with other ISO 15552 cylinders from various manufacturers.
