About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-40S
The AirTAC SAIJ100X450-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 410-450 mm usable travel window, allowing you to dial back the 450 mm nominal stroke by up to 40 mm during commissioning.
This specific SKU is configured with an SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and uses PT tapered G1/2 ports.

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 SAIJ100AX450-40S Is Used
Variable End-Stop Tuning
Dial in the exact 410 to 450 mm end position during machine commissioning to accommodate varying product lengths without swapping hardware.
Product Size Changeover
Quickly adjust the retract stop on automated lines to handle different package sizes, reducing setup time between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-40S the Right Cylinder?
An adjustable stroke is selected over a fixed SAI cylinder when you need fine end-position tuning for product changeovers without adding external stops. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series. Because the 450 mm stroke is substantial, ensure proper external guidance to prevent rod side-loading. To match this ISO 15552 replacement, verify the 100 mm bore, 450 mm stroke, 40 mm adjustment, PT G1/2 ports, and the -S magnet requirement.
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 SAIJ100AX450-40S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If higher pressure is applied, the push force reaches 5497 N at 0.7 MPa and 7068 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 450 mm nominal stroke by up to 40 mm, providing a usable travel window of 410 to 450 mm. It only sets the end position and does not lock the load without live air pressure.
