About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-20S
The AirTAC SAIJ32X175-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 155 to 175 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a standard magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The rear mechanical stopper allows you to trim the effective stroke without swapping the cylinder or adding external stops during product changeovers. Remember that this 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 SAIJ32BX175-20S Is Used
Machine Changeover
Fine-tune the 155-175 mm travel window during product size transitions without disassembling the line or swapping cylinders.
Variable End Stops
Set precise retract positions for multiple part sizes using the rear adjustment screw rather than external mechanical stops.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for light-duty pushing tasks in environments requiring higher corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-20S the Right Cylinder?
The adjustable stroke is ideal for machine setup and changeover, letting you dial in the exact 155-175 mm travel rather than machining custom fixed-length SAI cylinders. Because the stroke is 175 mm, side-load risks are moderate, but an external guide should still be used to prevent rod binding.
For a true ISO 15552 replacement, match the 32 mm bore, 175 mm nominal stroke, 20 mm adjustment range, PT port threads, SUS304 (B) rod material, and the -S magnet requirement. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires true load-holding without continuous air pressure, this cylinder will not suffice; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ32BX175-20S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the 175 mm nominal stroke by up to 20 mm, providing a usable travel window of 155 to 175 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
