About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-75S
The AirTAC SAIJ100X90-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within a 15 to 90 mm window. The integrated -S magnet supports position detection using AirTAC CMSE reed and DMSE solid-state sensors.
This unit features a SUS420J2 stainless steel rod for enhanced durability against moisture and PT tapered port threads for a tight, reliable seal. The rear adjustment screw lets you fine-tune the retract end-position at commissioning without adding external stops. Remember that this adjuster acts only as a travel stop and does not hold the load without live air pressure.

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 SAIJ100AX90-75S Is Used
Machine Changeover
Dial in the retract stroke from 15 to 90 mm instantly when switching a packaging line to a different carton size, eliminating the need to swap out physical spacers.
End-Position Tuning
Fine-tune the final resting position of a heavy press head during commissioning, using the rear screw to absorb kinetic energy via the 36 mm air cushion.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-75S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (offering 1559 N at 0.5 MPa) is too small, but a 125 mm bore is unnecessary. The 75 mm adjustment range is ideal for applications requiring significant travel flexibility or frequent product changeovers. If you need to hold a load securely without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is strictly a stop, not a brake.
For an exact ISO 15552 replacement match, verify the 100 mm bore, 90 mm stroke, 75 mm adjustment, G1/2 port, and the -S magnet option. The M20x1.5 rod thread and 25 mm rod diameter provide high rigidity, but because the nominal stroke of 90 mm is short, side-load stress is minimal even without an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ100AX90-75S FAQ
The rear stopper screw lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 15 to 90 mm. This allows precise end-position tuning at commissioning without changing the cylinder or adding external stops.
At 0.9 MPa, the push force increases to 7068 N.
