About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-75
The AirTAC SAIJ80X195-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. By integrating a 75mm adjustment range, this unit allows you to fine-tune the effective travel anywhere within a 120 to 195mm window directly at the machine, eliminating the need to physically swap cylinders during product changeovers.
This 80mm bore actuator features a G3/8 port and a durable 25mm piston rod with an M20x1.5 thread, utilizing an SUS420J2 stainless steel rod material for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the rear stopper functions strictly as an end-position deceleration device rather than a load-holding lock.

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 SAIJ80AX195-75 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 120 and 195mm during machine setup to accommodate different material lengths without installing external mechanical stops.
Product Size Changeovers
Quickly adjust the rear stroke stopper on a packaging line to handle varying carton dimensions, leveraging the 80mm bore's 2513N pull force at 0.5 MPa to cycle reliably.
Commissioning Fine-Tuning
Trim the effective travel by up to 75mm during initial commissioning to perfectly time the kinematic motion of a heavy-duty press without swapping out the entire actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX195-75 the Right Cylinder?
Selecting this 80mm bore actuator makes sense when your application requires substantial push force—such as 2513N at 0.5 MPa—but demands on-the-fly end-position tuning across a 120-195mm travel window. If your setup requires less force, stepping down to a 63mm bore provides 1559N at 0.5 MPa, whereas moving up to a 100mm bore yields 3927N at 0.5 MPa. Choose this adjustable-stroke SAIJ variant over a fixed SAI cylinder when you need precise commissioning flexibility without adding external stops.
For an exact ISO 15552 replacement, match the 80mm bore, 195mm stroke, 75mm adjustment, PT tapered port threads, and the specific mounting bracket (available options include Basic, FA, LB, TC, FTC, TCM1, and TCM2). Note that this model does not include a magnet (-S), so position sensing via CMSE or DMSE switches is not supported without modification. Because the stroke is 195mm, ensure adequate external guidance to prevent excessive side-loading on the rod. If true load-holding without live air pressure is required, consider an AirTAC SAIL or BSAI cylinder instead.

- ✓ 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 SAIJ80AX195-75 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 75mm. This creates a usable travel window of 120 to 195mm, enabling fine-tuning of the end position at commissioning without changing the cylinder.
At 0.9 MPa, the push force increases to 4523N. The cylinder operates at speeds between 30 and 800 mm/s.
