About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX35-20S
The AirTAC SAIJ100X35-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 15-35 mm usable travel window from the 35 mm nominal stroke, allowing you to dial back the retract end-position by up to 20 mm during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a piston magnet (-S) for electronic DMSE or reed CMSE position sensing. The extruded aluminum barrel integrates sensor grooves on both sides. It uses a PT tapered G1/2 port and offers self-adjustable air cushions at both ends to decelerate the load.

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 SAIJ100AX35-20S Is Used
Machine Setup & Changeover
Quickly fine-tune the 15-35 mm retract end-position during product-size changeovers without swapping out the entire cylinder or bolting on external stoppers.
Corrosive Environment Actuation
Utilize the SUS420J2 stainless steel rod and DMSE/CMSE compatible magnet to reliably drive testing fixtures in humid or mildly corrosive industrial settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX35-20S the Right Cylinder?
If you need less thrust, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa. The adjustable rear stopper is ideal for machine setups requiring variable end stops or product-size changeovers, functioning purely as a travel stop rather than a lock. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 35 mm stroke, 20 mm adjustment range, PT G1/2 port, and the -S magnet requirement. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 25 mm rod and M20x1.5 thread provide robust side-load capacity, this cylinder handles dynamic loads well, though any application should still rely on an external guide for optimal performance.
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 SAIJ100AX35-20S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 35 mm nominal stroke by up to 20 mm. This creates a 15-35 mm usable travel window for fine-tuning the end position at commissioning, but it does not lock or hold the load without live air pressure.
