About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-20
The AirTAC SAIJ32X150-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 130 to 150 mm during commissioning. This specific configuration includes a SUS304 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threading.
The extruded aluminum barrel integrates sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic sensors if a magnet is added later. Unlike a fixed-stroke SAI cylinder, the rear stopper screw lets you dial in the exact retract end-position without swapping hardware or adding external stops. Remember that the adjuster acts only as a travel stop; it does not hold the load without live air pressure.

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 SAIJ32BX150-20 Is Used
Machine Changeover
Quickly adjust the retract distance from 150 mm down to 130 mm when switching product sizes on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the exact end-of-stroke position during initial commissioning to compensate for mechanical tolerances in the fixture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-20 the Right Cylinder?
The 12 mm rod and M10x1.25 thread provide a robust interface for standard loads, but long unsupported strokes still require an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. For applications requiring true load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 Adjustable Cylinder SAIJ32 SAIJ32BX150-20 FAQ
The nominal stroke is 150 mm, but the rear adjuster allows you to shorten the effective travel by up to 20 mm, creating a usable adjustment window of 130 to 150 mm.
The rear adjuster only sets the travel end-point; it does not function as a lock or brake, so it will not hold a load without live air pressure.
