About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-100
The AirTAC SAIJ100X190-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 100 mm. This creates a highly flexible 90-190 mm usable window, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear screw sets the travel end and the variable air cushions decelerate the load, neither acts as a lock; maintaining position requires continuous live air.

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 SAIJ100AX190-100 Is Used
Product Changeovers
Dial in the exact 90 to 190 mm stroke required for different sized parts on the same line, using the rear screw to switch end positions rapidly without changing hardware.
Variable End Stops
Replace fixed mechanical stops with the integrated rear adjuster to create a flexible, shock-absorbing travel limit that adapts to evolving production needs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX190-100 the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application requires substantial thrust—such as 5497 N at 0.7 MPa—combined with variable end-stops for product changeovers. If your process needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The wide 90-190 mm adjustment range is perfect for prototyping or lines running multiple product sizes, whereas a fixed-stroke SAI is better for dedicated single-purpose stations. Because the nominal stroke is 190 mm, side-loading is moderate, but always ensure proper external guiding for optimal rod life.
To match this exact configuration for an ISO 15552 replacement, specify a 100 mm bore, 190 mm stroke, 100 mm adjustment range, PT port threads, SUS420J2 rod material, and no magnet. It supports the standard SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without continuous air pressure, consider an external rod lock or the AirTAC SAIL/BSAI series instead.

- ✓ 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 SAIJ100AX190-100 FAQ
If you need higher force, stepping up to a 125 mm bore yields 6136 N at the same pressure.
The rear adjuster acts as a stopper that lets you shorten the 190 mm nominal stroke by up to 100 mm, providing a usable travel window of 90 to 190 mm. It sets the end position but does not lock the load without live air pressure.
