About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-50
The AirTAC SAIJ100X75-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated rear adjusting screw allows you to dial back the nominal 75 mm travel, creating a flexible 25 to 75 mm usable window. This is ideal for fine-tuning end positions at commissioning without swapping the cylinder or adding external stops.
This model features a SUS420J2 stainless steel rod (option A) for enhanced durability against moisture, paired with PT tapered port threading (G1/2). The extruded aluminum barrel includes sensor grooves on both sides, though position sensing requires adding a magnet. Remember, the rear adjuster acts solely as a travel stop to set deceleration, not as a lock; it cannot hold a 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 SAIJ100AX75-50 Is Used
End-Position Tuning
Perfect for dialing in the exact 25-75 mm travel window during machine commissioning to prevent overtravel and crush damage.
Product Changeover
Quickly adjust the rear stopper to accommodate varying package sizes on a packaging line without changing hardware.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-50 the Right Cylinder?
If you need less thrust, step down to an 80 mm bore (2513N at 0.5 MPa). The 50 mm adjustment range is particularly valuable for machines handling frequent product changeovers, allowing operators to reposition the end-stop on the fly rather than maintaining an inventory of fixed-stroke SAI cylinders. Because the nominal stroke is under 300 mm, side-load concerns are minimal, but always ensure the load is guided externally for long-term reliability.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 75 mm stroke, 50 mm adjustment, PT port, and SUS420J2 rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a brake.
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 SAIJ100AX75-50 FAQ
At maximum 1.0 MPa pressure, it yields 801 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from 75 mm down to as little as 25 mm. It sets the travel end and deceleration point but does not lock the load without live air.
