About the Airtac SAI100 Standard Air Cylinder SAI100AX90S
The AirTAC SAI100X90-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 90mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This specific configuration includes a magnet for proximity sensing and utilizes a SUS420J2 stainless steel rod (material code A), offering superior corrosion resistance compared to standard carbon steel.
The extruded aluminum barrel integrates sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches without extra brackets. Fluid ports are PT threaded. As a genuine AirTAC component, it provides a reliable, drop-in mounting solution for any standardized ISO 15552 pneumatic architecture.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX90S Is Used
Heavy-Duty Pressing
Generates 5497 N of push force at 0.7 MPa, ideal for securely seating bearings or pressing components into rigid housings.
Pallet Diverting
The 90mm stroke quickly actuates heavy redirect gates on high-throughput packaging lines without occupying excessive machine footprint.
Automated Clamping
Provides the substantial holding power needed to secure large metal or composite workpieces during CNC machining operations.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX90S the Right Cylinder?
Selecting this 100mm bore provides 3927 N of push force at 0.5 MPa; if your application requires less force, stepping down to an 80mm bore yields 2513 N, while moving up to a 125mm bore offers 6136 N. The 90mm stroke is highly compact, minimizing rod-bearing bending stress during operation.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered. For applications requiring dead-stop holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model uses a PT G1/2 port and is dimensionally interchangeable with other ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAI100AX90S FAQ
At a standard 0.5 MPa operating pressure, this 100mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X90-S is built to the ISO 15552 profile standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders. It uses a G1/2 PT port and standard FA, FB, LB, and TC mounting accessories.
