About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-40S
The AirTAC SAIJ100X85-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N push force at 0.5MPa, utilizing a 25mm carbon steel rod and G1/2 PT tapered ports. Because this specific SKU carries a 40mm adjustment code on an 85mm nominal stroke, you gain a usable travel window of 45 to 85mm. This allows operators to dial in the exact retract position during commissioning without swapping out the entire actuator.
This extruded aluminum profile cylinder includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors housed in its dual-side sensor grooves. The rear adjuster functions purely as a mechanical stop to fine-tune the end-of-travel position; it is not a locking device and cannot hold a load without continuous live air pressure. For load-holding requirements without air, consider an external rod lock or the related SAIL pneumatic lock series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-40S Is Used
Product Changeover
Quickly re-tune the 45-85mm travel window during packaging line format changes to accommodate varying carton depths without replacing hardware.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to prevent crashes and ensure precise mechanical contact on high-force presses.
Adjustable Ejector
Serve as a variable-stroke ejection mechanism where the rear mechanical stop is dialed in to push parts varying distances based on the current run.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X85-40S the Right Cylinder?
Choose this 100mm bore actuator when an application demands high thrust, as stepping down to a 63mm bore yields only 1559N at 0.5MPa. The adjustable 45-85mm travel window is ideal for product-size changeovers on a line, letting you reposition the end-stop rapidly instead of adding external stops or buying a fixed-stroke SAI cylinder. When specifying an ISO 15552 replacement, match the 100mm bore, 85mm nominal stroke, 40mm adjuster, G1/2 PT ports, and the -S magnet requirement.
Mounting options for this SAIJ series are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Although the 25mm rod handles substantial side loads, any stroke approaching or exceeding 300mm on larger setups would require an external guide; at this 85mm stroke, the cylinder is compact enough for standard direct mounting.
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 SAIJ100X85-40S FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 5497N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 85mm down to as little as 45mm. It only sets the travel end position and does not lock the load without live air pressure.
