About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-75S
The AirTAC SAIJ32X325-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows you to dial in end positions during commissioning without adding external stops.
This SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions while providing sensor grooves on both sides for flexible switch placement. It operates at speeds of 30-800mm/s and uses a G1/8 port.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX325-75S Is Used
Product Changeovers
Dial in the 250-325mm travel window rapidly during format changes on packaging lines without physically replacing the cylinder.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to achieve exact positioning without machining external stop blocks.
Variable Length Diverters
Adjust the stroke on the fly to accommodate different package sizes moving down a conveyor without retooling the station.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-75S the Right Cylinder?
The 75mm adjustment range is ideal for product changeovers on a line, letting you shift the retract stop dynamically rather than swapping out a fixed-stroke SAI cylinder. Because the stroke is 325mm, ensure an external guide supports the load to prevent excessive side-loading on the rod.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder exactly, specify the 32mm bore, 325mm stroke, 75mm adjustment, PT tapered ports, and the -S magnet for CMSE reed or DMSE electronic sensors. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX325-75S FAQ
If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the 325mm nominal stroke by up to 75mm, providing a usable travel window of 250-325mm. It functions as a mechanical stop to set the end position and is not a lock.
