About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-50
The AirTAC SAIJ100X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 750-800 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning, while the SUS420J2 stainless steel rod (code A) provides excellent corrosion resistance for demanding environments.
This model uses a PT tapered port thread and relies on variable air cushions at both ends to decelerate the payload smoothly. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it is not a lock. For load-holding without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ100AX800-50 Is Used
Machine Setup & Changeover
Fine-tune the 750-800 mm travel end-stop during product size changeovers without physically swapping the cylinder or bolting on external stoppers.
Variable End-Stop Positioning
Dial in the exact retraction point for automated conveyor sorting arms where the target position shifts based on package dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-50 the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers on a line, allowing you to dial in the exact end-stop without adding external shims. When replacing an ISO 15552 cylinder, match the 800 mm stroke, PT port type, and desired mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the stroke is 800 mm, the 25 mm rod diameter must handle significant side loads. Even with the robust M20x1.5 rod thread, an external guide rail is highly recommended to prevent premature seal wear and binding over long unsupported travels.
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 SAIJ100AX800-50 FAQ
It reaches a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw lets you trim the effective travel back by up to 50 mm from the nominal 800 mm stroke, creating a 750-800 mm window. It functions as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
