About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-40S
The AirTAC SAIJ100X55-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 15-55 mm usable travel window, allowing you to fine-tune the retract end position by up to 40 mm without adding external stops.
This variant includes a SUS420J2 stainless steel rod for enhanced durability against moisture and features a magnet for AirTAC CMSE (reed) and DMSE (solid-state) sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

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 SAIJ100AX55-40S Is Used
Machine Changeovers
Dial in the exact retract position during product size transitions using the 40 mm adjustment window, eliminating the need to physically swap cylinders for new format runs.
Commissioning Calibration
Fine-tune the end-stop at startup to perfect sensor triggering and tool contact points without relying on makeshift external mechanical spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-40S the Right Cylinder?
The adjustable stroke is ideal for machine changeovers where the exact end-of-stroke position varies slightly. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
To match this ISO 15552 replacement exactly, verify your bore size, 55 mm nominal stroke, 40 mm adjustment range, PT tapered port threads, and the required -S magnet. Because the stroke is 55 mm, side-load risks are minimal, but standard alignment procedures should still be followed.
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 SAIJ100AX55-40S FAQ
The rear adjuster screw lets you mechanically shorten the 55 mm nominal stroke by up to 40 mm, creating a usable travel window of 15 to 55 mm. The adjuster sets the end-stop but does not lock the load without continuous air pressure.
