About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-30S
The AirTAC SAIJ32X400-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in rear stopper allows you to trim the effective travel, providing a usable window of 370-400mm for exact end-position tuning without swapping hardware.
This model includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the dual sensor grooves on the extruded aluminum barrel. The PT tapered port is G1/8, and the adjustable end-stop acts purely as a travel deceleration point, not a load-holding lock.

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 SAIJ32BX400-30S Is Used
Product Changeover
Dial in the 370-400mm travel window during line format changes to accommodate varying package sizes without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position at machine commissioning to achieve precise mechanical alignment using the rear stopper screw.
Sensor Integration
Leverage the -S magnet with DMSE electronic or CMSE reed switches in the dual grooves for reliable position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-30S the Right Cylinder?
Choose this 32mm bore when you need precise 370-400mm travel tuning at commissioning or during product changeovers, avoiding the need to bolt on external stops. Because the stroke is 400mm, the 12mm rod needs external guidance to prevent excessive side-loading on the seals.
For an exact ISO 15552 replacement, match the 32mm bore, 400mm stroke, 30mm adjustment, PT G1/8 port, and SUS304 rod. Remember that the rear adjuster only sets the end position; to hold a load without live air, use a SAIL lock cylinder or an external pilot-operated check valve. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX400-30S FAQ
The operational speed range is 30-800mm/s.
The rear adjuster screw lets you shorten the nominal 400mm stroke by up to 30mm, creating a 370-400mm travel window. It functions as a stop, not a lock.
