About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-40S
The AirTAC SAIJ32X280-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, providing a usable travel window of 240-280 mm. The integrated -S magnet supports position sensing with CMSE reed and DMSE electronic switches.
This model uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. The rear adjuster acts purely as a mechanical stop for fine-tuning end positions at commissioning; it does not hold the load without live air. For load-holding without pressure, consider SAIL or BSAI cylinders.

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 SAIJ32AX280-40S Is Used
End-Position Tuning
Fine-tune the retract stroke by up to 40mm during machine commissioning without adding external stops.
Product Changeover
Quickly adjust the 240-280mm travel window to accommodate varying product sizes on the same line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-40S the Right Cylinder?
The 40mm adjustment range is ideal for product changeovers, allowing variable end-stops without swapping cylinders. It omits FB, CA, CB, and CR mounts, using only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.
Since the 280mm stroke exceeds 300mm guidelines for side-load management, ensure external guides support the load. To match this ISO 15552 cylinder: 32mm bore, 280mm stroke, 40mm adjust, PT G1/8 port, SUS420J2 rod, and -S magnet.
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 SAIJ32AX280-40S FAQ
At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the nominal 280mm stroke by up to 40mm, creating a 240-280mm travel window. It functions as a stop, not a lock, so air pressure is still required to hold the load.
