About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-100S
The AirTAC SAIJ80X475-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 475 mm travel by up to 100 mm. This yields a precise usable stroke window of 375 to 475 mm, enabling fine end-position tuning at commissioning without swapping the barrel or adding external stops. In the 80 mm bore class, it delivers substantial thrust—generating 4523 N of push force at 0.9 MPa and 2268 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and carries the -S magnet option for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves. It uses a PT tapered G3/8 port and relies on a 36 mm variable air cushion at both ends to decelerate the load. Remember that the rear adjuster acts purely as a travel stop to set the end position; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-100S Is Used
Variable End-Stop Positioning
Dial in the exact 375 to 475 mm travel distance during machine setup to accommodate different package sizes without physically replacing the cylinder.
High-Force Clamping
Leverage up to 4523 N of push force at 0.9 MPa for securing heavy workpieces, using the rear screw to fine-tune the clamping depth precisely.
Product Changeover Systems
Rapidly adjust the stroke window on automated conveyor sorting lines to handle varying product lengths during production run transitions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-100S the Right Cylinder?
Select this 80 mm bore size when an application requires high thrust—stepping down to a 63 mm bore yields 2805 N push at 0.9 MPa, while stepping up to a 100 mm bore provides 7068 N. The 100 mm adjustment range is ideal for production lines running mixed product sizes, allowing operators to change the end-stop on the fly. For an exact ISO 15552 replacement, match the 80 mm bore, 475 mm nominal stroke, 100 mm adjustment, PT G3/8 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 475 mm, the 25 mm diameter rod is highly susceptible to side-loading; an external guide rail is strongly recommended to prevent premature seal wear. If you need true load-holding without live air, use an external rod lock or pilot-operated check valve, or switch to an AirTAC SAIL or BSAI series 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 SAIJ80AX475-100S FAQ
At 80 mm bore, it provides 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 100 mm, creating a usable travel window of 375 to 475 mm. It functions as a mechanical stop and does not hold the load without continuous air pressure.
