About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX100-20S
The AirTAC SAIJ32X100-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80 to 100 mm. The integrated -S magnet enables direct position sensing with AirTAC CMSE reed and DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered ports. The rear stopper screw allows you to dial in the exact end position during commissioning without adding external stops. Note that this adjuster acts purely as a travel stop and does not hold the load without continuous air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX100-20S Is Used
Machine Changeovers
Dial in the 80-100 mm stroke window on the fly during product size transitions without physically swapping out the cylinder assembly.
Precision End-Stops
Fine-tune the retract position during commissioning using the rear adjuster to achieve exact placement of lightweight 402 N components.
Sensor-Ready Positioning
Leverage the built-in magnet with DMSE electronic sensors to confirm stroke endpoints across the adjusted travel range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX100-20S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning within an 80-100 mm travel range. Because the stroke is 100 mm, side-load risks are minimal, but an external guide remains recommended for optimal piston life. To match this exact ISO 15552 interchangeable cylinder, specify: 32 mm bore, 100 mm stroke, 20 mm adjustment, PT ports, and the -S magnet option.
The adjustable stroke is ideal for machine changeovers where product sizes vary, preventing the need to physically swap cylinders. For applications requiring true load-holding without live air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL pneumatic lock or an external pilot-operated check valve instead.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX100-20S FAQ
If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 20 mm, creating an 80-100 mm usable travel window. It functions as a travel stop, not a lock, and does not hold the load without live air pressure.
