About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-75
The AirTAC SAIJ80X160-75 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the nominal 160 mm stroke by up to 75 mm. This creates a wide usable travel window of 85 to 160 mm, perfect for accommodating product size changes on a line without physically swapping the actuator.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered port threads on its G3/8 ports. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches if a magnet is added later. The rear stopper simply acts as a travel end deceleration point, not a lock, so live air is required to hold the load.

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 SAIJ80AX160-75 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 85 and 160 mm during product changeovers, eliminating the need to bolt on external stops or swap out the entire cylinder.
Machine Setup Fine-Tuning
Use the 75 mm rear adjustment screw to perfectly time the stroke end during initial commissioning, compensating for mechanical tolerances without reprogramming the PLC.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-75 the Right Cylinder?
The adjustable 85-160 mm travel window is ideal for machine setups requiring frequent commissioning fine-tunes or variable end-stops, saving you from maintaining a large inventory of fixed-stroke SAI cylinders for every product format.
When ordering a replacement, ensure you match the 80 mm bore, 160 mm nominal stroke, 75 mm adjustment range, PT port threads, and SUS420J2 rod material. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 160 mm, side-load is minimal, but always rely on an external guide for heavy loads, as the 25 mm rod cannot support high lateral forces alone. For dead-pilot or load-holding without live air, select a SAIL or BSAI cylinder instead.
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 SAIJ80AX160-75 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw allows you to shorten the effective travel from the 160 mm nominal stroke by up to 75 mm, providing a usable stroke window of 85 to 160 mm. The adjuster acts only as a travel stop and does not lock the load without live air pressure.
