About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-20
The AirTAC SAIJ40X60-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 40 to 60 mm usable travel window.
This adjustable unit omits the FB, CA, CB, and CR mounts, offering a reduced ISO 15552 mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear stopper allows precise end-position tuning during commissioning without adding external stops.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40AX60-20 Is Used
Machine Changeovers
Dial in the 40 to 60 mm travel window during product size transitions without physically swapping the cylinder or adding external stopper blocks.
Commissioning Setup
Fine-tune the retract end-position precisely during initial machine setup to absorb minor mechanical tolerances in the fixture.
Variable End Stops
Provide a adjustable mechanical stop for light assembly tooling that requires precise positioning within the 60 mm stroke limit.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-20 the Right Cylinder?
The 20 mm adjustment window is ideal for machine changeovers where the exact end-of-stroke position varies slightly between product runs.
Because the SAIJ40X60-20 lacks a magnet for sensors, position verification requires external switches. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI cylinder. It is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ40 Adjustable Cylinder SAIJ40AX60-20 FAQ
A rear external stopper screw lets you shorten the effective travel from the nominal 60 mm down to 40 mm, creating a 40 to 60 mm adjustable window for fine-tuning at commissioning.
