About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-40S
The AirTAC SAIJ100X75-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 75 mm travel by up to 40 mm. This creates a highly versatile 35-75 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without swapping hardware. It delivers robust thrust, pushing with 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via a PT G1/2 port. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, meaning live air is required to hold the load.

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 SAIJ100AX75-40S Is Used
Product Changeovers
Quickly adapt the end-of-stroke position from 35 to 75 mm during line format changes without physically replacing the cylinder.
Machine Setup
Fine-tune the exact clamping or ejection point during commissioning using the rear stopper screw to avoid costly mechanical rework.
Variable End Stops
Handle multiple product sizes on a single station by adjusting the effective stroke window to match the specific component geometry.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-40S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial force, such as 3927 N at 0.5 MPa, but you need finer control over the end-stop than a fixed SAI cylinder provides. Conversely, if you exceed 7068 N at 0.9 MPa, consider a larger frame. The adjustable stroke is ideal for product changeovers where exact positioning varies.
Because the stroke is 75 mm, side-load stress is minimal, but the 25 mm rod and M20x1.5 thread handle robust loads. Remember that the rear adjuster is a stop, not a brake; for load-holding without live air pressure, use an external rod lock or explore the SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552, uses a PT tapered port, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ100AX75-40S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 40 mm. For a 75 mm nominal stroke, this provides a usable stroke window of 35 to 75 mm, allowing you to set the exact retract position at commissioning.
At 0.9 MPa, the push force increases to 7068 N.
