About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-75
The AirTAC SAIJ160X325-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down from a 325 mm nominal stroke to a 250-325 mm operating range. This configuration uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads.
The rear adjustment screw acts purely as a mechanical stop to dial in the end position during commissioning or product changeovers without swapping the cylinder. It does not hold the load without live air pressure. Extruded from aluminum with sensor grooves on both sides, this unit omits the FB, CA, CB, and CR mounting options, utilizing a reduced set of ISO 15552 interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2).

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX325-75 Is Used
Variable End-Stop Forming
Dial in the exact 250 to 325 mm travel window during press setup, allowing precise material forming without machining custom external spacers.
Product Changeover
Quickly adjust the rear stop screw when switching the production line to a different package size, reducing machine downtime between runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-75 the Right Cylinder?
The 75 mm adjustment range is ideal for lines running mixed product sizes, allowing variable end-stops without adding external physical stops. For any load-holding requirements without live air pressure, the rear adjuster is insufficient; you must specify a SAIL pneumatic lock, BSAI clamp-lock cylinder, or an external rod lock.
Because the 325 mm stroke exceeds 300 mm, the 40 mm diameter rod and M36x2 thread will experience amplified leverage on the piston under side loads. An external guide rail is strongly recommended to prevent rod binding and premature seal wear. Operating speed is capped at 30-500 mm/s for this large bore.
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 SAIJ160 Adjustable Cylinder SAIJ160BX325-75 FAQ
It can deliver a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from 325 mm down to a minimum of 250 mm. It sets the travel end but does not lock the load without continuous air pressure.
