About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-20S
The AirTAC SAIJ100X75-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By integrating a 20mm adjustment mechanism, this unit allows you to fine-tune the effective travel down from its 75mm nominal length, creating a precise 55-75mm usable window without requiring external stops.
This specific configuration includes an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a built-in magnet (-S) for position sensing. It operates at speeds between 30-800 mm/s and utilizes a PT G1/2 port. The extruded aluminum barrel features sensor grooves on both sides, seamlessly supporting AirTAC CMSE reed and DMSE electronic solid-state switches.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX75-20S Is Used
Product Changeovers
Dial in the 55-75mm stroke window during format size changes on a packaging line, avoiding the need to physically swap cylinders for different carton depths.
End-Stop Calibration
Fine-tune the final retracted position during machine commissioning, using the rear screw to perfectly align a 3927N clamping action without adding external stopper blocks.
Sensor-Driven Positioning
Leverage the integrated magnet and dual sensor grooves to mount DMSE electronic switches, confirming the adjusted end-of-travel position in automated assembly cells.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-20S the Right Cylinder?
If you need to step down force, the 80mm bore offers 2513N at 0.5 MPa; stepping up to 125mm yields 6136N. The adjustable 55-75mm travel window is perfect for machine setups requiring frequent product changeovers, replacing the need to swap out a fixed-stroke SAI cylinder.
For an exact ISO 15552 dimensional replacement, match the 100mm bore, 75mm stroke, 20mm adjustment, PT G1/2 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ100 Adjustable Cylinder SAIJ100AX75-20S FAQ
If you increase the pressure to 0.7 MPa, the push force rises to 5497N.
The rear adjuster screw allows you to shorten the 75mm nominal stroke by up to 20mm, creating a 55-75mm usable travel window. This stopper only sets the end position and does not lock the load without continuous air pressure.
