About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-75
The AirTAC SAIJ100X185-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 110-185 mm usable travel window from its 185 mm nominal stroke.
This model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and works alongside the standard air cushions to set deceleration, but it does not hold the load without live air. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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.

Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-75 the Right Cylinder?
If your process needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, while moving up to a 125 mm bore provides 6136 N. The adjustable stroke is perfect for variable end-stops and product changeovers, whereas a fixed SAI cylinder is better for rigid, unchanging setups.
For load-holding without continuous air pressure, this cylinder is insufficient; you should look at the SAIL or BSAI series instead. To match this ISO 15552 footprint exactly, specify a 100 mm bore, 185 mm stroke, 75 mm adjustment, PT ports, and the SUS420J2 rod material. Since the stroke is under 300 mm, side-load concerns are minimal, but long unsupported loads still require an external guide.
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 SAIJ100AX185-75 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm, creating a usable travel window of 110 to 185 mm. It functions as a travel stop for end-position tuning, not as a lock to hold the load without air pressure.
