About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-50S
The AirTAC SAIJ32X400-50-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the 400 mm nominal travel by up to 50 mm for a precise 350-400 mm usable window. The integrated magnet (-S) supports position sensing.
This bore size features a 12 mm rod, M10x1.25 rod thread, and PT tapered ports. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock the load without live air. For load-holding without pressure, consider an external pilot-operated check valve or the SAIL series.

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 SAIJ32BX400-50S Is Used
Changeover Calibration
Dial in the 350-400 mm travel window during product size changes without swapping the cylinder or adding external mechanical stops.
End-Position Trimming
Fine-tune the exact retract position at machine commissioning to compensate for mechanical tolerance stack-up using the rear screw.
Variable Diverting
Adjust the diverting stroke on the fly for different package sizes on a packaging line, relying on the 50 mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-50S the Right Cylinder?
The adjustable stroke is ideal when a fixed SAI cylinder would require external stop blocks to fine-tune travel.
Because the 400 mm stroke is relatively long for a 12 mm rod, you should use an external guide to prevent excessive side-loading and premature seal wear. This SAIJ configuration uses PT ports and includes the -S magnet for CMSE reed and DMSE solid-state sensors. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32BX400-50S FAQ
At 0.7 MPa, the push force increases to 563 N.
A rear adjuster screw lets you shorten the 400 mm nominal stroke by up to 50 mm, creating a 350-400 mm usable travel window. It acts as a mechanical stop and does not hold the load without live air pressure.
