About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-40
The AirTAC SAIJ80X325-40 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 285-325mm usable travel window, allowing you to dial back the 325mm nominal stroke by up to 40mm during commissioning.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX325-40 Is Used
Variable End-Stop Tuning
Dial in the exact 285-325mm retract position during machine commissioning to accommodate varying part sizes without adding external stopper blocks.
Product Changeover Setup
Quickly adjust the stroke end-point on a packaging line when switching to a new carton format, saving downtime compared to replacing the entire cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX325-40 the Right Cylinder?
Because the 325mm stroke is non-standard and exceeds the 1200mm typical long-stroke threshold for this series, an external guide is recommended to manage side-load on the 25mm rod over this extended travel.
The rear adjuster acts purely as a mechanical stop to set the travel end and cannot hold a load without live air pressure; for true load-holding, select the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It operates at 30-800mm/s without a magnet.
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 SAIJ80BX325-40 FAQ
The rear adjusting screw allows you to mechanically shorten the effective stroke from the 325mm nominal length by up to 40mm, creating a 285-325mm usable travel window. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
