About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75
The AirTAC SAIJ80X190-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, pushing 4523N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides for straightforward detection integration.
With a 190mm nominal stroke and a 75mm adjustment range, this model provides a usable travel window of 115-190mm. This wide tuning band allows operators to dial in the exact retract end-position during commissioning or product changeovers without swapping the cylinder or adding external stops. The standard carbon steel rod and M20x1.5 rod thread provide excellent structural rigidity, while the PT tapered port ensures a tight pneumatic seal.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75 Is Used
Variable Product Changeover
Quickly reconfigure the 115-190mm retract end-stop on packaging lines when switching between different carton or part sizes without changing the cylinder.
Machine Setup Calibration
Fine-tune the final seating position of heavy tooling during initial commissioning using the rear screw, ensuring perfect alignment without external shims.
Adjustable Diverter Stroke
Control the extension length of a sorting diverter arm on a conveyor to accommodate varying package widths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-75 the Right Cylinder?
Selecting this 80mm bore over a 63mm neighbor (which provides 2805N push at 0.5 MPa) is ideal when your application demands higher force output and greater side-load resilience. The 75mm adjustment window is particularly valuable for machines processing varying product sizes, as it allows the retract end-stop to be reconfigured quickly without machining new hard stops. Since the nominal stroke is below 300mm, external guiding requirements are less stringent than on longer strokes, though the M20x1.5 rod still benefits from a linear guide for off-center loads.
When ordering, verify the 190mm stroke, 75mm adjustment, PT port thread, and carbon steel rod material. Note that the rear adjuster functions strictly as a travel stop to set the end position, not as a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ80X190-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75mm. This creates a usable travel window of 115-190mm, letting you set the exact retract end-position at commissioning without adding external stops.
At 0.9 MPa operating pressure, the SAIJ80X190-75 provides a push force of 4523N and a pull force of 3681N. It operates at a speed range of 30-800 mm/s.
