About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-75S
The AirTAC SAIJ100X210-75-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 135 to 210 mm, allowing you to dial back the nominal 210 mm stroke by up to 75 mm during machine setup.
This specific configuration includes a SUS420J2 stainless steel rod (material option A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel features dual sensor grooves, and because this is an -S variant, it includes a magnet ready for CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops.

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 SAIJ100AX210-75S Is Used
Machine Changeover
Dial in the exact 135 to 210 mm travel window during product size changes without physically swapping actuators or bolting on external stopper blocks.
Adjustable End Stops
Set precise retract end-positions on the fly. The PT ported cylinder handles the main thrust while the 75 mm adjustment range absorbs setup variances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX210-75S the Right Cylinder?
Choose this 100 mm bore actuator when your application requires substantial thrust, such as 5497 N at 0.7 MPa, but demands variable end-position tuning. If you need less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas a 125 mm bore provides 6136 N for heavier loads. The adjustable stroke is ideal for product changeovers, letting you shorten travel without swapping the cylinder.
Since the 210 mm stroke exceeds 300 mm? No, but even at 210 mm, long unsupported loads require an external guide to prevent side-loading damage to the 25 mm rod. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting FB, CA, CB, and CR. The rear adjuster and air cushions decelerate the load but do not hold it without live air; for dead-load holding, select a SAIL or BSAI cylinder. It is dimensionally interchangeable per ISO 15552.
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 SAIJ100AX210-75S FAQ
It features a rear adjusting screw that lets you shorten the effective travel from the 210 mm nominal stroke down to a minimum of 135 mm, giving a 75 mm tuning window. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 5497 N.
