About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-40S
The AirTAC SAIJ100X40-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 40mm stroke that can be dialed back by up to 40mm, yielding a highly versatile 0-40mm usable travel window for precise end-position tuning at commissioning.
This variant includes a -S magnet for CMSE reed and DMSE solid-state sensors, utilizing the dual sensor grooves machined into the extruded aluminum barrel. The piston rod is built from SUS420J2 stainless steel for corrosion resistance, and the PT tapered port threads ensure a robust, sealed pneumatic connection. The rear adjuster functions strictly as a mechanical stop to set travel limits and is not a locking mechanism, meaning the cylinder cannot hold loads 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 SAIJ100AX40-40S Is Used
Variable End-Stop Forming
Dial in the exact 0-40mm travel window for pressing or forming operations during product changeovers without adding external mechanical stops.
Machine Setup Calibration
Fine-tune the rear adjuster during commissioning to perfect end-of-stroke positioning, absorbing mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-40S the Right Cylinder?
Selecting this 100mm bore model is ideal when an application requires high thrust (up to 3927N at 0.5MPa) combined with variable end-stops for rapid product-size changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. If your process demands less force, stepping down to an 80mm bore yields 2513N at 0.5MPa; conversely, a 125mm bore provides 6136N for heavier loads. For load-holding without continuous air pressure, consider the SAIL or BSAI clamp-lock series instead. As an ISO 15552 replacement, verify the 100mm bore, 40mm stroke, 0-40mm adjustment range, PT G1/2 port, and the -S magnet requirement.
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 SAIJ100AX40-40S FAQ
The rear adjuster acts as a mechanical stop that trims the effective travel. For this model, a nominal 40mm stroke can be reduced by up to 40mm, providing a 0-40mm usable travel window. It sets the end position but does not lock the load without live air.
At 0.9MPa, the push force increases to 7068N.
