About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50
The AirTAC SAIJ80X220-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated external stopper allows you to shorten the effective travel, providing a usable adjustment window of 170 to 220 mm for this specific configuration.
This model features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. It carries the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, while omitting FB, CA, CB, and CR brackets. The extruded aluminum barrel includes sensor grooves on both sides for future-proofing, though this unit is specified without a magnet.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX220-50 Is Used
Machine Changeover
Quickly reconfigure the retract end-stop by up to 50 mm when switching between product sizes on a packaging line, eliminating the need for custom spacer rings.
Clamp Positioning
Fine-tune the exact clamping distance against varying workpiece thicknesses, using the 170-220 mm travel window to prevent over-travel damage.
Assembly Station Setup
Dial in the precise end-of-stroke position during initial commissioning to perfectly align a heavy 2513 N press fit without swapping out the entire actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50 the Right Cylinder?
Choose this 80 mm bore when an application requires high thrust (up to 2513 N at 0.5 MPa) but demands variable end-positioning during commissioning or product changeover. The 50 mm adjustment range lets you dial in the exact retract distance without adding external stops or swapping the cylinder. For any stroke at or above 300 mm, you should add an external guide to prevent excessive side-loading on the rod.
Because this is a standard double-acting cylinder, the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. If your machine requires true fail-safe load holding, you must use a related AirTAC type like the SAIL (air-released lock) or BSAI (clamp-lock). This SAIJ80X220-50 is dimensionally interchangeable per ISO 15552 and is configured with a PT port, no magnet, and a SUS420J2 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 SAIJ80 Adjustable Cylinder SAIJ80AX220-50 FAQ
The rear of the cylinder features an external adjusting screw that acts as a mechanical stopper. For this model, you can trim the effective travel back by up to 50 mm, creating a usable stroke window of 170 to 220 mm. It only sets the travel end and does not lock the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
