About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-20S
The AirTAC SAIJ32X165-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 145-165 mm window without adding external stops. Driven by a 12 mm carbon steel core, this specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsher environments.
Equipped with a magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-sided sensor grooves. The extruded aluminum barrel design omits tie-rods, and the rear adjuster functions strictly as a travel stop to dial in end positions during machine commissioning.

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 SAIJ32BX165-20S Is Used
Machine Commissioning
Dial in the exact 145-165 mm end-stop during initial setup to perfect striking distance without machining custom spacers.
Product Changeover
Quickly retract the stroke by up to 20 mm on packaging lines when switching to a slightly shorter product variant.
Sensor-Driven Sorting
Pairs with DMSE electronic sensors to verify retracted positions across variable travel distances on small conveyor diverter arms.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-20S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning at setup or during product changeovers, rather than relying on a fixed-stroke SAI variant.
To replace an ISO 15552 cylinder of the same footprint, match the 32 mm bore, 165 mm stroke, 20 mm adjustment range, PT tapered port thread, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and cannot hold a load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. Because the 165 mm stroke is under 300 mm, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
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 SAIJ32BX165-20S FAQ
If you increase the pressure to 0.9 MPa, the push force reaches 724 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 165 mm stroke by up to 20 mm, creating a usable travel window of 145-165 mm. It only sets the end position; it does not lock the load without air pressure.
