About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-75S
The AirTAC SAIJ32X550-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows precise end-position tuning during commissioning without adding external stops.
This SKU features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides, and the PT G1/8 port ensures straightforward pneumatic integration.

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 (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 SAIJ32AX550-75S Is Used
Machine Changeover
Dial in the 475-550mm travel window during product size changes without physically swapping the cylinder or reworking fixed stop blocks.
Variable End Stops
Set precise retract positions for multi-format assembly lines using the rear adjuster rather than machining custom external spacers.
Commissioning Tuning
Fine-tune the final end-of-stroke position during setup to perfect tooling alignment while keeping the standard ISO 15552 footprint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-75S the Right Cylinder?
The rear screw acts purely as a travel stop for deceleration and end-position setting, not as a lock. It will not hold a load without live air pressure, so for fail-safe load holding you should use an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. Because this cylinder has a 550mm stroke, the 12mm rod requires external guiding to prevent excessive side-loading and premature seal wear.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 32mm bore, 550mm stroke, 75mm adjustment range, PT G1/8 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ32AX550-75S FAQ
At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the effective stroke by up to 75mm from the 550mm nominal length, creating a 475-550mm travel window. It functions as a mechanical stop for position tuning and does not lock the load without continuous air pressure.
