About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-40S
The AirTAC SAIJ100X80-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, engineered to provide a usable travel window of 40 to 80 mm from its 80 mm nominal stroke. Built with a carbon steel rod and PT tapered port threads, it delivers robust thrust up to 7068 N at 0.9 MPa. The integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic sensors for precise position detection.
This adjustable-stroke design allows operators to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop to set the end position, not a lock, meaning the cylinder cannot hold loads without live air. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-40S Is Used
Product Changeover
Dial in the 40 to 80 mm travel window on the rear screw to quickly adapt end positions for different product sizes without changing hardware.
End-Stop Tuning
Fine-tune the retract stroke during machine commissioning to hit exact material forming depths, avoiding the need for external mechanical stops.
High-Force Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or fixtures, using the adjustable travel to dial in the exact stopping point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-40S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires high force combined with variable end-position tuning, stepping up from a 80 mm bore that provides 4523 N push at 0.9 MPa. The adjustable 40 to 80 mm travel window is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is better suited for rigidly defined repeatable travel. Because the stroke is under 300 mm, side-load stress on the 25 mm rod is manageable, though external guides are still recommended for heavy lateral loads. For load-holding without live pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a brake. To match this ISO 15552 replacement, specify the 100 mm bore, 80 mm stroke, 40 mm adjustment, G1/2 PT port, desired mounting, and the -S magnet.

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 SAIJ100X80-40S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 40 mm, creating a usable stroke window of 40 to 80 mm. It acts as a mechanical stop to fine-tune the end position, but it is not a lock and will not hold the load without continuous air pressure.
At 0.9 MPa operating pressure, the SAIJ100X80-40-S provides a push force of 7068 N and a pull force of 3681 N. It operates at speeds between 30 and 800 mm/s.
