About the Airtac SAI40 Standard Air Cylinder SAI40AX120S
The AirTAC SAI40X120-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 120mm stroke. It delivers a robust push force of 879 N at 0.7 MPa, making it well-suited for mid-range industrial handling tasks. The extruded aluminum barrel design omits tie-rods for a clean, compact exterior.
This specific configuration includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance in humid environments. It also features a built-in magnet (-S) for use with CMSE and DMSE reed sensors, and utilizes PT tapered port threads. Genuine AirTAC quality ensures reliable pneumatic performance.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX120S Is Used
Parts Clamping
Provides 879N of push force at 0.7MPa, securely holding workpieces during light machining or assembly operations.
Package Diverting
The 120mm stroke offers precise actuation for routing cartons or totes on automated material handling lines.
Vertical Lifting
SUS420J2 stainless steel rod withstands humid warehouse environments when elevating goods to staging platforms.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX120S the Right Cylinder?
Selecting this bore size is ideal when an SAI32 cylinder lacks sufficient thrust (offering only 563 N push at 0.7 MPa), but you want to avoid stepping up to the larger 50mm bore. The 120mm stroke provides ample travel for standard clamping and lifting tasks. Because the stroke is under 300mm, standard rod bearing bending loads are minimal, though heavy radial loads still require an external guide.
As a standard double-acting cylinder, this model relies on continuous air pressure to hold its position; if air is exhausted or a valve is centered, the piston will drift. For applications requiring true position holding without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model is dimensionally interchangeable per ISO 15552, featuring a G1/4 port, M12x1.25 rod thread, and compatibility with FA/FB flange or TC trunnion mounts.
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.
