Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-30
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX65-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 65mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-30
It features a SUS420J2 stainless steel rod and PT tapered port threads. By turning the rear screw, you can trim the nominal 65mm stroke back by up to 30mm, creating a precise 35-65mm usable travel window for exact end-position tuning during commissioning.
This adjustable stopper allows you to dial in the retract position without swapping cylinders or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though this specific SKU is supplied without a magnet. 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 SAIJ100AX65-30 Is Used
Product Changeovers
Quickly adapt the retract distance from 35 to 65mm when swapping product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the exact stopping point of a heavy press or clamp during machine commissioning to achieve perfect alignment.
Variable End Stops
Set custom retract limits for automated assembly stations without installing external physical stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-30 the Right Cylinder?
The 30mm adjustment range is perfect for product-size changeovers on a line, letting you shift the end-stop dynamically rather than relying on a fixed-stroke SAI cylinder.
For an exact ISO 15552 replacement, match the 100mm bore, 65mm stroke, 30mm adjustment, PT port, and your preferred mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Because the rear screw is a stop and not a lock, use a SAIL or BSAI cylinder if you need fail-safe load holding without continuous air pressure.
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 SAIJ100AX65-30 FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 65mm nominal stroke by up to 30mm, providing an effective travel window of 35-65mm. This lets you set the exact end position at commissioning without changing the cylinder.
