About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-75S
The AirTAC SAIJ80X130-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down from 130 mm to a minimum of 55 mm. This wide 75 mm adjustment range is ideal for product changeovers on automated lines, letting you set precise end-stops at commissioning without swapping hardware or adding external stops.
Built with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this -S variant includes a magnet for position sensing. It is fully compatible with AirTAC CMSE reed switches and DMSE solid-state electronic sensors that drop directly into the dual-side sensor grooves on the extruded aluminum barrel. The 25 mm rod and M20x1.5 thread provide high structural rigidity, handling greater side loads than smaller bores, though long unsupported strokes still require an external guide.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-75S Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 55 and 130 mm during machine setup to accommodate varying material thicknesses without changing out the entire actuator.
Product Size Changeovers
Quickly adjust the stroke length on packaging or sorting lines to handle different carton sizes, using the rear stopper to reconfigure the travel window on the fly.
Commissioning Fine-Tuning
Trim the nominal 130 mm stroke by up to 75 mm to perfectly sync the cylinder's end-of-stroke position with adjacent tooling and fixtures during initial line integration.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-75S the Right Cylinder?
Select this 80 mm bore when an application requires substantial thrust combined with variable end-positioning. The SAIJ80X130-75-S is chosen over a fixed-stroke SAI specifically when the usable travel window of 55-130 mm needs on-the-fly mechanical tuning rather than a locked, single-position stroke.
Because the rear adjuster acts purely as a travel stop and the variable air cushions only manage deceleration, neither feature will hold a load in place without live air pressure. If your setup requires true fail-safe load holding, you must integrate an external rod lock, a pilot-operated check valve, or switch to the SAIL (air-released lock) or BSAI (clamp-lock) cylinder variants. When replacing an ISO 15552 cylinder, match the 80 mm bore, 130 mm stroke, 75 mm adjustment, G3/8 PT ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ80AX130-75S FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver up to 513 kgf of push force.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke from its nominal 130 mm down to a minimum of 55 mm, creating a 75 mm adjustable travel window. It functions only as a travel stop and does not lock or hold the load without continuous air pressure.
