About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10S
The AirTAC SAIJ80X475-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 4523N push force at 0.9 MPa and provides a usable travel window of 465 to 475 mm, letting you dial back the stroke by up to 10 mm during commissioning. This model includes a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
Because the 475 mm stroke is relatively long, the 25 mm rod diameter and M20x1.5 thread provide necessary rigidity, though an external guide is recommended to manage side loads. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE electronic switches. You can fine-tune the retract end position without swapping hardware or adding external stops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10S Is Used
Machine Setup Calibration
Fine-tune the 465-475 mm travel window during initial commissioning to perfectly dial in the retract end position without machining custom spacers.
Product Size Changeover
Quickly adjust the stroke end-stop by up to 10 mm when a production line switches to a slightly different package or component size.
Long-Stroke Assembly Press
Leverage the 4523N push force at 0.9 MPa for pressing operations while using the rear stopper to set precise final positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-10S the Right Cylinder?
Choose this 80 mm bore when the 50 mm class (982N at 0.5 MPa) is insufficient but the 100 mm class (3927N at 0.5 MPa) is oversized. The adjustable 10 mm end-stop is ideal for product changeovers or fine-tuning machine setup, whereas a fixed SAI cylinder locks you into a single exact dimension. The PT tapered port threads (G3/8) and standard mounting interface ensure straightforward replacement.
For any stroke of 475 mm, you must account for side-load inertia; always use an external guide rail to prevent rod binding. Remember that the rear adjuster acts only as a travel stop, not a lock. If your application requires load-holding without live air pressure, select the SAIL pneumatic lock or BSAI clamp-lock cylinder instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ80AX475-10S FAQ
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates a push force of 4523N and a pull force of 4071N. At 0.5 MPa, it provides 2513N of push force and 2268N of pull force.
The rear adjusting screw acts as an external stopper that lets you mechanically shorten the effective stroke from 475 mm down to 465 mm. This allows precise end-position tuning at commissioning or during product changeovers without replacing the cylinder.
