About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-40S
The AirTAC SAIJ32X120-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows you to dial in exact end positions during commissioning without adding external stops.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and offers variable air cushions at both ends to manage deceleration. Note that the rear adjuster acts only as a travel stop, not a load-holding lock; maintaining position requires continuous air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32BX120-40S Is Used
Product Changeovers
Quickly adjust the 80-120mm travel window to accommodate different product sizes on a packaging line without swapping the cylinder.
Machine Commissioning
Fine-tune the exact retract end-stop during initial setup to perfect sensor alignment and gripping positions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-40S the Right Cylinder?
If your application requires less force, stepping down is not an option in this size range, but if you need substantially more thrust, the 40mm bore provides 628N. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder is better for dedicated single-purpose tasks. When replacing an ISO 15552 cylinder, match the 32mm bore, 120mm stroke, 40mm adjustment, PT ports, and the -S magnet.
Because the 120mm stroke is relatively short for the 32mm bore, side-load risks are minimal, but the 12mm rod and M10x1.25 thread still require external guiding if subjected to lateral forces. For load-holding without live air pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ32BX120-40S FAQ
At 0.7 MPa, the push force increases to 563N.
The rear adjuster allows you to shorten the 120mm nominal stroke by up to 40mm, providing an adjustable travel window of 80-120mm. It functions as a physical stop and does not lock the load without air pressure.
