About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-75
The AirTAC SAIJ80X325-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel anywhere within a 250-325 mm window. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch placement.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The 25 mm rod diameter and M20x1.5 rod thread provide excellent structural rigidity. Because the 325 mm stroke is relatively long, maintaining an external guide is recommended to prevent excessive side-loading on the rod.

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 SAIJ80BX325-75 Is Used
Variable End-Stop Machining
Dial in the exact 250-325 mm clamping reach during machine setup, accommodating different part lengths without retooling the entire fixture.
Product Changeover Lines
Quickly adjust the rear stopper position on packaging conveyors to handle varying box sizes on the fly, minimizing downtime between production runs.
Commissioning Fine-Tuning
Precisely trim the retract end-position during initial commissioning to perfect timing sequences, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers on a line, letting operators dial in the exact end-stop without swapping cylinders or adding external mechanical stops.
When specifying a replacement, match the 80 mm bore, 325 mm nominal stroke, 75 mm adjustment range, PT G3/8 port, and SUS304 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pneumatic locking, consider the SAIL or BSAI series. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX325-75 FAQ
It operates efficiently at speeds between 30 and 800 mm/s.
The rear adjuster screw allows you to mechanically shorten the nominal 325 mm stroke by up to 75 mm, providing a usable travel window of 250 to 325 mm. It functions as a hard stop for end-position tuning and is not a locking device.
