About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-20
The AirTAC SAIJ80X160-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 160 mm travel back by up to 20 mm, creating a precise 140-160 mm usable window.
This model uses PT tapered port threads (G3/8) and relies on a variable air cushion at both ends to decelerate the load. The rear stopper acts purely as a travel end-limit, meaning it does not hold the load without continuous live air pressure. For load-holding requirements without air, an external rod lock or related series like SAIL or BSAI should be specified instead.

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 SAIJ80AX160-20 Is Used
Machine Changeover
Dial in the 140-160 mm travel window during product size changes to set exact end positions without physically swapping out the cylinder.
Conveyor Diverting
Actuate diverters and gates with fine-tuned travel limits, ensuring packages are gently stopped without needing external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-20 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than the 63 mm bore (1402 N pull at 0.5 MPa) but less than the 100 mm bore (3681 N pull). The 20 mm adjustment range is ideal for machine setup and product changeovers, allowing operators to fine-tune the end position without swapping cylinders or adding external stops. It supports a speed range of 30-800 mm/s.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 160 mm stroke, 20 mm adjustment, G3/8 PT ports, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load stress is moderate, but an external guide is still recommended for heavy unsupported loads.
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 SAIJ80AX160-20 FAQ
At the maximum 1.0 MPa pressure, the push force reaches 5026 N.
The rear adjuster screw allows you to shorten the 160 mm nominal stroke by up to 20 mm, providing a usable travel window of 140 to 160 mm. This stopper only limits the travel end and does not lock or hold the load without live air pressure.
