About the Airtac SAI100 Standard Air Cylinder SAI100AX375
The AirTAC SAI100X375 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927N at 0.5 MPa and 5497N at 0.7 MPa, making it well-suited for high-thrust applications requiring a 375mm stroke. The extruded aluminum barrel eliminates tie-rods, providing a smooth exterior that simplifies cleaning and sensor mounting.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it operates without integrated position sensing. For high-temperature environments up to 120°C, the seals can be specified in Viton (code H) instead of the standard TPU.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX375 Is Used
Heavy Stamping
Provides the 5497N force at 0.7 MPa needed to actuate large stamping presses and form rigid metal components over a 375mm travel distance.
Material Forming
Drives heavy forming dies and molding platens where the SUS420J2 stainless steel rod offers superior resistance to moisture and workshop coolant.
Pallet Handling
Indexes heavy loaded pallets along conveyor lines, utilizing the adjustable air cushions to smoothly stop the 100mm bore at the end of its 375mm extension.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX375 the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm version increases your 0.5 MPa push thrust from 2513N to 3927N, while stepping up to the 125mm bore yields 6136N. At a 375mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external guide rail or use a dedicated guided cylinder to absorb lateral forces.
As a true ISO 15552 profile cylinder, the SAI100X375 offers a dimensionally interchangeable mounting interface, serving as a drop-in replacement for other ISO 15552 cylinders. It uses a G1/2 port and supports standard mounting accessories like FA flange or TC trunnion. Note that the adjustable air cushions only decelerate the piston at stroke ends; they will not hold a load if air pressure is lost. Use the SAIL or BSAI variants if dead-end locking is required.
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 SAI100AX375 FAQ
At 0.5 MPa, the push force is 3927N and the pull force is 3681N. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497N.
Yes. The SAI100X375 is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, provided your mounting and G1/2 port requirements align.
