Airtac SAIJ80 Adjustable Cylinder SAIJ80AX225-100
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX225-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX225-100
The AirTAC SAIJ80X225-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 225 mm travel by up to 100 mm. This yields a usable window of 125-225 mm, enabling precise end-position tuning at commissioning without swapping out the barrel or bolting on external stops. It delivers a robust 2513 N pull force at 0.5 MPa, making it well-suited for heavy positioning tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is built without a magnet. The rear adjuster acts purely as a mechanical stop to set the retract end, meaning it will not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

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 SAIJ80AX225-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 125 to 225 mm during machine setup to accommodate different material thicknesses without changing hardware.
Product Changeover
Quickly adjust the stroke stopper when switching the production line to a new item size, minimizing downtime and eliminating the need for custom spacer blocks.
Heavy Positioning
Leverage the 2513 N pull force at 0.5 MPa to push and pull heavy jigs or fixtures into their precise working positions before clamping.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX225-100 the Right Cylinder?
The generous 100 mm adjustment range is ideal for production lines running mixed product sizes, letting operators fine-tune the retract distance on the fly instead of maintaining separate fixed-stroke SAI cylinders for each job.
Because the 225 mm stroke falls under the 300 mm threshold, side-loading stress is moderate, but the 25 mm rod and M20x1.5 thread still provide a rigid interface. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed ranges from 30-800 mm/s, and the cylinder relies on variable air cushions at both ends to decelerate the load.

- ✓ 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 SAIJ80AX225-100 FAQ
A rear external stopper screw lets you shorten the effective travel from the nominal 225 mm down to as little as 125 mm. This mechanical stop sets the retract end position but does not lock the load without continuous air pressure.
