About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100S
The AirTAC SAIJ80X105-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly flexible usable travel window of 5 to 105 mm. Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore unit is designed for applications demanding exact end-position tuning without swapping hardware. The PT tapered port threads and carbon steel rod come standard.
Featuring a built-in magnet (-S), it operates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves. The rear stopper allows precise stroke trimming during commissioning, though it functions strictly as a travel stop and does not lock the load without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100S Is Used
Variable End-Stop Tuning
Dial in the precise 5 to 105 mm travel window during machine setup to accommodate varying material thicknesses without installing external physical stops.
Product Changeovers
Quickly adjust the rear stopper to handle different package sizes on a packaging line, leveraging the 2513 N push force to move heavy goods efficiently.
Sensor-Driven Positioning
Utilize the integrated magnet with CMSE or DMSE sensors to confirm end-of-stroke positions across the entire adjustable range in automated assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-100S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial thrust—such as the 2513 N push force at 0.5 MPa—combined with extreme stroke variability. If you need less force, stepping down to a 63 mm bore yields 1559 N; stepping up to a 100 mm bore provides 3927 N. The 100 mm adjustment range is perfect for product-size changeovers on a packaging line, replacing the need for fixed-stroke SAI cylinders when end-stops fluctuate.
For an exact ISO 15552 replacement match, ensure you specify the 80 mm bore, 105 mm nominal stroke, 100 mm adjustment, PT port threads, and the -S magnet option. Because the nominal stroke is 105 mm, standard external guiding is less critical than on longer strokes, but always support the load adequately. Remember that neither the rear adjuster nor the variable air cushions act as a brake; for true load-holding without live air, 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 SAIJ80 Adjustable Cylinder SAIJ80X105-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjusting screw acts as a mechanical stopper, allowing you to trim the effective travel down from the 105 mm nominal stroke to as little as 5 mm. This creates a 5-105 mm usable window, enabling fine-tuning at commissioning without replacing the cylinder.
