About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-50
The AirTAC SAIJ80X160-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 160 mm stroke that can be fine-tuned down by up to 50 mm, creating a precise 110-160 mm usable travel window. The barrel is extruded aluminum with sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance.
This model uses a G3/8 port and an M20x1.5 rod thread, supporting a robust side-load capacity. The rear adjuster acts purely as a mechanical stop to set the retraction end position during commissioning without needing external stops. It supports a speed range of 30-800 mm/s and features adjustable air cushions at both ends to decelerate moving loads smoothly.

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 SAIJ80AX160-50 Is Used
Product Changeover
Dial in the 110-160 mm retraction stop during format size changes on a packaging line without physically swapping the actuator.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfectly time the 2513 N clamping force against varying workpiece heights.
Variable End Stops
Adjust the rear mechanical stop on the fly to accommodate different material lengths in automated material handling equipment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-50 the Right Cylinder?
If your process requires less force, stepping down to a 63 mm bore yields 1559 N. The adjustable stroke is ideal for machine setups requiring frequent product changeovers, replacing the need to swap out a fixed-stroke SAI cylinder. For any stroke of 160 mm or more, ensure external guides support the load to prevent excessive rod wear.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 160 mm nominal stroke, 50 mm adjustment range, PT tapered port thread, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that the SAIJ series omits FB, CA, CB, and CR mounts. Because this cylinder lacks a magnet, it cannot host CMSE or DMSE sensors without a -S designation. The rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX160-50 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 160 mm nominal stroke by up to 50 mm, providing a usable travel window of 110-160 mm. It sets the end position but does not lock the load without live air pressure.
