About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-40S
The AirTAC SAIJ100X85-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 85 mm stroke that can be fine-tuned down by up to 40 mm, giving operators a precise 45-85 mm usable travel window during commissioning.
This variant is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the unit operates at speeds between 30 and 800 mm/s with G1/2 ports.

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 SAIJ100AX85-40S Is Used
Product Changeovers
Quickly adjust the end-of-stroke position within the 45-85 mm window to accommodate different product sizes on the same conveyor line without changing hardware.
Assembly Station Setup
Dial in the exact retraction point during commissioning to prevent over-travel and ensure components are pressed together accurately every cycle.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-40S the Right Cylinder?
The adjustable 45-85 mm travel window is ideal for product changeovers on a packaging line, allowing you to dial in the exact end position without swapping the cylinder for a fixed-stroke standard SAI model. Because the stroke is under 300 mm, side-load stress is minimal, though the robust 25 mm rod and M20x1.5 thread naturally tolerate higher offset loads.
For direct replacements, match the 100 mm bore, 85 mm nominal stroke, 40 mm adjustment range, PT tapered port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Note that the rear adjuster acts only as a travel stop; it does not hold the load without continuous air pressure. For secure load-holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100AX85-40S FAQ
The rear adjuster screw allows you to shorten the 85 mm nominal stroke by up to 40 mm, creating a usable travel window of 45 to 85 mm. This stopper sets the end position but does not lock the load without live air pressure.
