About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-50S
The AirTAC SAIJ100X375-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.
This model is equipped with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and features PT tapered port threads. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. The rear adjuster acts purely as a mechanical stop to fine-tune the retract stroke, meaning it cannot hold a load without continuous 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 SAIJ100AX375-50S Is Used
Product Changeover
Quickly reconfigure the 325-375mm travel window for varying product lengths without physically replacing the cylinder or adding external stopper blocks.
Machine Setup
Fine-tune the retract end position during initial commissioning to achieve perfect alignment, utilizing the rear screw rather than re-engineering the fixture.
Variable End Stops
Ideal for automated lines processing different material widths, allowing operators to dial in the exact stroke limit on the fly for precise positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-50S the Right Cylinder?
If you need less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, whereas larger requirements would necessitate a 125mm bore providing 6136N. The adjustable stroke is perfect for product-size changeovers on a line, replacing the need for fixed-stroke SAI cylinders when exact end positions fluctuate.
Because this unit features a 375mm stroke, the 25mm rod and M20x1.5 thread should be paired with an external guide to prevent excessive side-loading on the piston. For load-holding without live pressure, this SAIJ model is insufficient; you must integrate an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamping cylinder. To match this ISO 15552 interchangeable unit, specify the 100mm bore, 375mm stroke, 50mm adjustment, PT G1/2 port, desired mounting, and the -S magnet.
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 SAIJ100AX375-50S FAQ
If pressure is increased to 0.7 MPa, the push force rises to 5497N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 50mm. This creates a usable travel window of 325 to 375mm from the nominal 375mm stroke, but it does not lock the load without live air pressure.
