About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-100
The AirTAC SAIJ100X750-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 650 to 750 mm, allowing you to dial back the nominal 750 mm stroke by up to 100 mm during commissioning.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of switches. Remember that the rear adjuster acts purely as a travel stop for deceleration, not a lock, so live air pressure is required to hold 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 SAIJ100AX750-100 Is Used
Machine Changeover
Dial in the exact end position for different product sizes on a packaging line without physically swapping out the actuator.
End-Stop Tuning
Fine-tune the 650 to 750 mm travel window during commissioning to perfect the seating force on heavy assemblies.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-100 the Right Cylinder?
The 100 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, eliminating the need to swap cylinders or add external stops. When replacing an ISO 15552 cylinder, match the 750 mm stroke, 100 mm bore, PT G1/2 port, and mounting style.
Because the stroke is 750 mm, the 25 mm rod needs external guidance to prevent excessive side-loading and premature seal wear. If your application requires the load to be held mechanically without air pressure, use an AirTAC SAIL or BSAI cylinder instead of relying on the SAIJ adjuster. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX750-100 FAQ
The maximum operating pressure is 1.0 MPa.
The rear adjuster acts as an external stop that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 650 to 750 mm. It is a travel stop, not a lock, so the cylinder requires live air to hold a load.
