About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-40S
The AirTAC SAIJ100X950-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end position during commissioning. It provides a usable travel window of 910 to 950 mm, allowing precise dialing back of the 950 mm nominal stroke by up to 40 mm without adding external stops.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-800 mm/s and uses PT tapered port threads (G1/2) for secure pneumatic connections.

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 SAIJ100AX950-40S Is Used
Machine Changeover
Dial in the exact 910 to 950 mm end-stop during product size transitions without physically swapping the cylinder or repositioning hard stops.
Material Positioning
Fine-tune the retract position of heavy pallet stops on long conveyor lines to accommodate varying pallet dimensions.
Assembly Line Tuning
Adjust the stroke end-point on the fly during commissioning to perfect the clamping or pressing force of heavy assemblies.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-40S the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore yielding 4523 N at 0.9 MPa is insufficient, but stepping up to a 125 mm bore (11045 N at 0.9 MPa) would be excessive. An adjustable stroke is ideal for product changeovers where the exact end-of-stroke position varies slightly, replacing the need to swap out a fixed-stroke SAI cylinder. For a direct ISO 15552 replacement, match the 100 mm bore, 950 mm stroke, 40 mm adjustment, PT G1/2 ports, and the -S magnet requirement.
Because the 950 mm stroke is substantial, the 25 mm diameter rod and M20x1.5 thread provide rigidity, but an external guide is highly recommended to prevent side-load damage over long unsupported travels. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold the load without live air pressure. For true load-holding without continuous air, consider an external rod lock or pilot-operated check valve. The available SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ100AX950-40S FAQ
It can deliver a maximum force of 801 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the 950 mm nominal stroke by up to 40 mm, creating a usable travel window of 910 to 950 mm. This stop sets the end position and does not lock or hold the load without continuous air pressure.
