About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-50
The AirTAC SAIJ100X220-50 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 220 mm stroke that can be dialed back by up to 50 mm, creating a precise 170-220 mm usable travel window for commissioning flexibility.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set the end position 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 SAIJ100AX220-50 Is Used
Product Changeovers
Dial in the 170-220 mm travel window during format changes on a packaging line, fine-tuning the retract position without replacing hardware.
Machine Setup
Use the rear stopper to precisely set the end position during commissioning, absorbing minor mechanical variances without repositioning the cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-50 the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a line, allowing you to shift the end-of-stroke position without swapping the cylinder or adding external stopper blocks. For load-holding without continuous air pressure, this cylinder is insufficient; the rear screw is a travel stop, not a lock, so you would need an external rod lock or a SAIL/BSAI series cylinder.
To replace an ISO 15552 cylinder, match the 100 mm bore, 220 mm stroke, 50 mm adjustment, G1/2 PT ports, and mounting style. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 220 mm stroke is relatively long, ensure external guiding to prevent excessive side-loading on the rod.
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 SAIJ100AX220-50 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this 220 mm nominal stroke cylinder, you can trim the travel back by up to 50 mm, yielding a usable 170-220 mm end-position window without changing the cylinder itself.
