About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-10
The AirTAC SAIJ32X140-10 is a double-acting ISO 15552 profile cylinder with a 32mm bore and a 140mm nominal stroke. It features a rear adjusting stopper that allows you to trim the effective travel back by up to 10mm, creating a precise 130-140mm usable stroke window. This built-in adjustability lets you fine-tune end positions at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches if a magnet is added later.
In this A-version configuration, the piston rod is made of SUS420J2 stainless steel, and the fluid porting uses PT tapered threads. The rear adjuster acts purely as a travel stop to set deceleration and end-position, not as a lock, so it will not hold a load without live air pressure. For true load-holding without pressure, consider the SAIL or BSAI series.

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 SAIJ32AX140-10 Is Used
Machine Setup Tuning
Dial in the exact 130-140mm end position during initial commissioning to perfect a pressing or clamping operation without machining external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's travel window on packaging lines when switching between slightly different product lengths, saving changeover time.
Precision End-Stop Trimming
Use the 10mm rear adjustment screw to compensate for minor mechanical tolerances in the fixture, ensuring repeatable positioning at the retract end.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-10 the Right Cylinder?
The SAIJ32X140-10 uses PT tapered ports and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards.
If your application needs to hold a load statically without continuous air pressure, this cylinder's rear adjuster will not serve as a brake; you would need an external rod lock or a different series like the SAIL. For this 140mm stroke, the 12mm rod diameter handles standard loads well, but for longer unsupported strokes over 300mm, an external guide is recommended to manage side 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 SAIJ32AX140-10 FAQ
The rear of the cylinder features an external adjusting screw that acts as a mechanical stopper. For this model, you can shorten the 140mm nominal stroke by up to 10mm, giving you an adjustable travel window of 130-140mm to fine-tune the retract end position.
