About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-100S
The AirTAC SAIJ100X325-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This wide adjustment band is ideal for dialing in exact end positions during machine commissioning or product changeovers without swapping hardware.
Configured for harsher environments, this unit includes a SUS420J2 stainless steel rod (option A) and a built-in magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply connects via PT G1/2 tapered ports, while the variable air cushions at both ends manage deceleration across the 30-800 mm/s speed range.

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 SAIJ100AX325-100S Is Used
Variable End-Stop Positioning
Leverage the 225-325 mm travel window to dial in the exact retraction point for multi-format packaging machinery without machining new hard stops.
Product Line Changeover
Rapidly adjust the rear stroke stopper by up to 100 mm when switching between different product sizes on an automated assembly line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-100S the Right Cylinder?
Because the 325 mm stroke is relatively long, the 25 mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is recommended to prevent excessive side-loading on the unsupported piston rod.
The adjustable rear stopper allows precise end-position tuning without adding external stops, unlike a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement, match the 100 mm bore, 325 mm stroke, 100 mm adjustment range, PT G1/2 port, and -S magnet. Note 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 AirTAC SAIL or BSAI locking cylinder. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX325-100S FAQ
If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the 325 mm nominal length by up to 100 mm, providing an adjustable travel window of 225-325 mm. It only sets the travel end and does not lock the load without continuous air pressure.
