About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-20
The AirTAC SAIJ32X135-20 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to fine-tune the end-of-travel position. The 20mm adjustment screw lets you dial back the 135mm stroke, creating a usable 115-135mm travel window for precise commissioning without adding external stops.
This 32mm bore variant uses a PT tapered port and a SUS304 stainless steel rod for corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if you add a magnet later. The rear adjuster acts purely as a travel stop and 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 SAIJ32BX135-20 Is Used
End-Position Tuning
Dial in the exact 115-135mm retract position during commissioning to absorb mechanical tolerances without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop on a packaging line when running different package lengths, minimizing downtime.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-20 the Right Cylinder?
If your process demands less force, stepping down is not an option in this frame size, but if you need significantly more thrust, the 40mm bore provides 628N at 0.5MPa. Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when a fixed stroke cannot absorb mechanical tolerances or varying product sizes on a single line.
For ISO 15552 replacement matching, verify the 32mm bore, 135mm stroke, 20mm adjustment range, PT port thread, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300mm, side-loading is less severe, but the 12mm rod still requires an external guide for heavy lateral loads. Remember that the adjuster is a stop, not a lock; for true load-holding without live air, consider an external rod lock or a SAIL cylinder.
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 SAIJ32BX135-20 FAQ
The rear adjuster screw lets you shorten the 135mm nominal stroke by up to 20mm, providing a usable travel window of 115-135mm. It functions as a mechanical stop to fine-tune the end position and is not a lock that holds the load without air pressure.
