About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-20
The AirTAC SAIJ100X190-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 170 to 190 mm, allowing you to dial back the nominal 190 mm stroke by up to 20 mm during commissioning.
This unit uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threads and lacks a piston magnet, meaning position sensing via CMSE or DMSE switches is not supported on this specific configuration. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX190-20 Is Used
End-Stop Tuning
Dial in the exact 170 to 190 mm retraction point during machine commissioning without adding external spacers or changing the cylinder.
Product Changeover
Quickly adjust the stroke window on packaging lines when handling different package sizes, using the rear screw to set new end positions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-20 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your machine setup requires variable end stops or frequent product-size changeovers, as the rear screw allows fine end-position tuning without swapping hardware. To match this exact ISO 15552 replacement, specify the 100 mm bore, 190 mm stroke, 20 mm adjust, PT ports, and no magnet.
Because the 190 mm stroke is under 300 mm, side-load stress on the 25 mm rod is moderate, though an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air pressure. For true load-holding without continuous air, consider an external rod lock or the AirTAC SAIL or BSAI series.
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 SAIJ100AX190-20 FAQ
At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw lets you shorten the effective travel from the 190 mm nominal stroke down to 170 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
