About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-40
The AirTAC SAIJ100X190-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 150-190 mm usable travel window, allowing you to dial back the 190 mm nominal stroke by up to 40 mm during commissioning.
This SKU is built with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and uses PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop for end-position tuning; it does not hold the load without live air, so load-holding requires a SAIL or BSAI variant.

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 SAIJ100AX190-40 Is Used
Machine Changeover
Dial in the 150-190 mm travel window during product size transitions without physically swapping out the cylinder.
Variable End Stops
Use the 40 mm rear adjuster to fine-tune the retract position for precise tooling alignment at commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-40 the Right Cylinder?
Select this 100 mm bore model when your application requires substantial thrust but exact end-positioning varies by product. The 40 mm adjustment range is ideal for machine changeovers, replacing the need to swap fixed-stroke SAI cylinders or bolt on external stops. Because the stroke is 190 mm (under 300 mm), side-load stress is moderate, but the 25 mm rod diameter handles standard dynamic loads well. For true load-holding without continuous air pressure, integrate an external rod lock or choose a SAIL cylinder.

- ✓ 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 SAIJ100AX190-40 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster lets you shorten the 190 mm nominal stroke by up to 40 mm, creating a 150-190 mm usable travel window. It acts as a mechanical stop and does not lock the load without air pressure.
