About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-30
The AirTAC SAIJ100X750-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 720 to 750 mm usable travel window, allowing you to dial back the retract end-position by up to 30 mm during commissioning without adding bulky external stops.
This SKU is configured with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches. Variable air cushions at both ends manage deceleration across the 30-800 mm/s speed range, while the rear adjuster acts purely as a travel stop and does not hold the 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 SAIJ100AX750-30 Is Used
Machine Changeover
Fine-tune the 720-750 mm retract position during product size changes on a packaging line without physically replacing the cylinder.
End-Stop Tuning
Dial in the exact end-of-stroke position during initial commissioning to compensate for mechanical tolerance stack-up in a long-stroke assembly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-30 the Right Cylinder?
The 30 mm adjustment window is ideal for product changeovers on a line where the exact retract distance varies slightly by part size, saving the effort of swapping a fixed-stroke SAI cylinder. Because the 750 mm stroke is substantial, always support the load with an external guide to prevent excessive side-loading on the M20x1.5 rod thread.
For ISO 15552 dimensional interchangeability, match the 100 mm bore, 750 mm stroke, PT G1/2 port, and mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If the machine requires true position holding without continuous air pressure, the rear adjuster will not act as a lock; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve instead.

- ✓ 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 SAIJ100AX750-30 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 750 mm down to 720 mm. It only sets the end position and deceleration; it does not lock or hold the load without live air pressure.
