About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-75S
The AirTAC SAIJ100X700-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This unit includes a SUS420J2 stainless steel rod for corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors.
The extruded aluminum barrel carries sensor grooves on both sides for flexible switch mounting. Because the rear screw acts purely as a mechanical stop to fine-tune the travel end, it does not hold the load without live air. For position holding without pressure, consider an external rod lock or the related SAIL lock cylinder. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ100AX700-75S Is Used
Machine Changeover
Dial in the 625 to 700 mm stroke window during product size changes without bolting on new external physical stops.
Variable End Stops
Fine-tune the retract position on the fly to accommodate varying package lengths on a sorting line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-75S the Right Cylinder?
An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers without physically swapping the cylinder or adding external stops. To match this ISO 15552 replacement exactly, verify the 100 mm bore, 700 mm stroke, 75 mm adjustment, PT tapered ports, and the -S magnet option.
With a 700 mm stroke, the 25 mm rod and M20x1.5 thread provide robust support, but long unsupported travel demands an external guide to prevent side-load damage. The rear adjuster and variable air cushions at both ends manage deceleration, but neither functions as a lock or 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 SAIJ100AX700-75S FAQ
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 75 mm, creating a 625 to 700 mm travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
