About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX1000-40
The AirTAC SAIJ100X1000-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 1000 mm nominal stroke that you can dial back by up to 40 mm, creating a 960-1000 mm usable travel window for precise end-position tuning.
This variant features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It uses PT tapered port threads (G1/2) and lacks a standard magnet. The rear adjuster acts purely as a mechanical stop to fine-tune the retract distance during commissioning; it does not hold the load without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX1000-40 Is Used
Long-Stroke Machine Setup
Dial in the exact retract position of a 1000 mm stroke actuator during equipment commissioning without installing external mechanical stops.
Product Size Changeover
Quickly adapt the travel end-stop by up to 40 mm on a packaging line when transitioning between different product dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX1000-40 the Right Cylinder?
Choose this 100 mm bore model when your application requires substantial thrust—3927 N at 0.5 MPa—and a long travel distance with fine-tuning capability. Because this cylinder features a 1000 mm stroke, you must use an external guide to support the rod and prevent excessive side-loading, as the 25 mm rod diameter cannot absorb large lateral forces alone.
Select the adjustable-stroke SAIJ over a fixed-stroke SAI when you need to trim the end-stop during machine setup or product changeover without adding external stops or swapping the cylinder. For true load-holding without continuous air pressure, this cylinder is insufficient; the rear adjuster is not a lock, so you should explore an AirTAC SAIL or BSAI series cylinder instead. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100 Adjustable Cylinder SAIJ100AX1000-40 FAQ
The 40 mm adjustment range allows you to trim the 1000 mm nominal stroke down to a minimum of 960 mm, giving a 960-1000 mm usable travel window.
No, the rear adjuster is a mechanical stop that sets the end-of-travel position and works with the air cushion to decelerate the piston. It is not a locking device and cannot hold a load without live air pressure. For load-holding, consider the SAIL or BSAI series.
