About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-40
The AirTAC SAIJ32X90-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel from 90 mm down to 50 mm.
This adjustable-stroke variant uses a stainless SUS420J2 rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE reed or DMSE electronic switches is not supported without modification.

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 SAIJ32AX90-40 Is Used
End-Position Tuning
Fine-tune the retract distance between 50 and 90 mm during commissioning to achieve precise material positioning without machining new hard stops.
Machine Changeover
Quickly adapt the cylinder's stroke when switching product sizes on a packaging line, using the rear screw to set the new travel limit.
Variable Assembly Feed
Adjust the feed length on the fly for different component heights, ensuring consistent clamping or pressing force across a batch.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-40 the Right Cylinder?
The 40 mm adjustment window is ideal for machine changeover, allowing operators to dial in the exact end position without swapping cylinders or adding external stops. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints but uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The 12 mm rod thread (M10x1.25) handles moderate side loads, but because the 90 mm stroke is relatively short, external guiding is typically unnecessary.
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 SAIJ32AX90-40 FAQ
The rear adjuster screw acts as a mechanical stopper, allowing you to trim the effective stroke back by up to 40 mm. This creates a usable travel window between 50 mm and 90 mm, but it does not lock the load without continuous air pressure.
