About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-100
The AirTAC SAIJ100X105-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 105 mm nominal stroke that can be dialed back by up to 100 mm, providing a wide 5-105 mm usable travel window for precise end-position tuning during commissioning.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors if needed. The rear stopper sets the travel end, but it does not hold the load without live air pressure.

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 SAIJ100AX105-100 Is Used
Product Changeover
Quickly dial the stroke from 105 mm down to 5 mm to accommodate varying package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to achieve perfect alignment of heavy press tools.
Variable End Stops
Use the 5-105 mm adjustable window to test multiple stopping distances in automated assembly stations before finalizing the design.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-100 the Right Cylinder?
The adjustable stroke is ideal for dialing in exact positioning without swapping cylinders, whereas a fixed SAI cylinder is better for repetitive, single-depth tasks. Remember that the rear adjuster acts only as a travel stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 105 mm stroke, 100 mm adjustment range, PT G1/2 port, and mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the 105 mm stroke is relatively short for this bore size, side-load risks are minimal, but external guides are still recommended for heavy off-center loads.
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 SAIJ100AX105-100 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjusting screw acts as a mechanical stopper that trims the effective travel. For this SAIJ100X105-100 model, you can shorten the 105 mm nominal stroke by up to 100 mm, resulting in a usable travel window of 5 to 105 mm.
