About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-20S
The AirTAC SAIJ32X170-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 150-170 mm from the 170 mm nominal stroke. The PT tapered port threads match the standard G1/8 interface for this bore size.
Because the rear screw acts as a travel stop rather than a load lock, it allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept AirTAC CMSE reed switches or DMSE solid-state sensors. This configuration omits the FB, CA, CB, and CR mounting styles, utilizing a reduced set of ISO 15552 mounts including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX170-20S Is Used
Machine Changeover
Dial in the retract distance within the 150-170 mm window during product size changes without physically swapping the cylinder or adding external stopper blocks.
Sensor-Ready Positioning
Utilize the integrated magnet with CMSE reed or DMSE solid-state sensors in the dual barrel grooves to confirm end-of-stroke positions after fine-tuning the travel stop.
Corrosion-Resistant Actuation
Deploy the SUS304 stainless steel rod in washdown or corrosive manufacturing environments where precise end-position tuning is required.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-20S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, providing a variable end-stop that fixed-stroke SAI cylinders cannot offer. For holding loads without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead, as the rear adjuster here only sets the travel end. Since the nominal stroke is 170 mm, side-loading is minimal, but long unsupported strokes should still use an external guide.
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 SAIJ32BX170-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel by up to 20 mm, creating a 150-170 mm usable window. It only sets the end position and does not lock or hold the load without live air pressure.
