About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-20S
The AirTAC SAIJ80X165-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This extruded aluminum body includes sensor grooves on both sides and is equipped with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
The rear adjuster functions strictly as a mechanical stop to fine-tune the end position and works alongside the standard variable air cushions at both ends. It does not hold the load without live air pressure; for load-holding requirements, consider the SAIL or BSAI series. This unit includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, and utilizes PT tapered ports.

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 SAIJ80AX165-20S Is Used
Product Changeover
Quickly dial in the 145-165mm travel window during format changes on a packaging line, using the rear screw to set new end positions without swapping hardware.
Variable End Stops
Adjust the effective stroke dynamically on automated machinery where slight positional variations are needed between different production cycles.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-20S the Right Cylinder?
If your setup demands less force, stepping down to a 63mm bore yields 1559N. The 20mm adjustment window is ideal for product changeovers on a line, allowing you to dial in the exact 145-165mm stroke length on the fly instead of physically swapping cylinders.
When specifying a replacement, ensure you match the 80mm bore, 165mm nominal stroke, 20mm adjustment code, PT port thread, and the -S magnet option. Mounting choices for this series are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Although the 25mm rod and M20x1.5 thread handle high side loads well, any stroke at or above 300mm requires an external guide to prevent rod bending.
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 SAIJ80AX165-20S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 145 to 165 mm. It requires live air to function and does not lock the load in place.
