About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-40
The AirTAC SAIJ40X60-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 60 mm stroke that can be fine-tuned backward by up to 40 mm, yielding a highly versatile 20-60 mm usable travel window.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. It supports a speed range of 30-800 mm/s and uses PT tapered port threads (G1/4) for reliable pneumatic sealing.

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 SAIJ40AX60-40 Is Used
Product Changeover
Dial in the exact end-stop position for varying part sizes on a packaging line without adding external mechanical stops.
Commissioning Calibration
Fine-tune the 20-60 mm travel window during machine setup to perfect the seating force of delicate components.
Variable Positioning
Adjust the retract position on the fly for multi-format production runs using the rear stopper screw.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX60-40 the Right Cylinder?
The 40 mm adjustment range on a 60 mm stroke is ideal for machine setups requiring extreme end-position variance during commissioning without swapping cylinders.
Because the rear screw acts only as a travel stop and the air cushions manage deceleration, this cylinder cannot hold a load without live air pressure. For drop prevention, consider the SAIL or BSAI locking series. This model is dimensionally interchangeable per ISO 15552, features PT ports, and omits FB, CA, CB, and CR mounting options.
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 SAIJ40AX60-40 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 128 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm. This creates a usable travel window between 20 mm and 60 mm, letting you set the exact end position without replacing the cylinder.
