About the Airtac SAI100 Standard Air Cylinder SAI100AX225S
The AirTAC SAI100X225-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. Delivering a robust 3927 N of push force at 0.5 MPa, it drives substantial loads over a 225 mm stroke. The extruded aluminum barrel omits tie-rods for a clean, modern exterior while maintaining strict dimensional interchangeability with standard ISO 15552 interfaces.
This specific configuration includes a -S magnet for seamless integration with CMSE and DMSE reed switches via the dual-side sensor grooves. It is built with an SUS420J2 stainless steel rod (option A) to resist corrosion in humid or mildly chemically exposed settings, and utilizes PT tapered port threads for a reliable, tight pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX225S Is Used
Heavy-Duty Pressing
Provides the necessary 3927 N of thrust at 0.5 MPa for securely seating bearings and bushings into rigid housings on automated assembly lines.
Pallet Diverting
Generates enough force to actuate heavy lane diverts and sorting gates for fully loaded pallets handling bulk materials.
Plastic Mold Clamping
Holds intermediate mold halves firmly in place during injection molding processes, utilizing the 225 mm stroke for precise mold closure.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX225S 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, whereas stepping up to the 125 mm bore yields 6136 N. Because the 225 mm stroke is relatively short, rod-bearing bending is minimal, but always verify that your load is axially aligned to prevent premature seal wear.
As a standard double-acting cylinder, this model relies on live air pressure to hold its position; if pneumatic supply is lost, the piston will drift. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This unit serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders, matching the 100 mm bore, 225 mm stroke, G1/2 port, and standard mounting accessories like FA flanges or TC trunnions.

- ✓ 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 SAI100AX225S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
No, the standard SAI cylinder uses adjustable air cushions to decelerate the piston at stroke ends, but it cannot lock or hold a load without constant air pressure. For fail-safe vertical load holding, use the SAIL (with lock) or BSAI (clamp-lock) variants.
