About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-10
The AirTAC SAIJ80X750-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 740-750mm, allowing you to trim the effective stroke by up to 10mm. This fine-tuning capability is ideal for dialing in exact end positions during commissioning without swapping hardware.
This unit is built with an SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear adjuster functions strictly as a mechanical stop to set the travel end and does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-10 Is Used
Machine Setup Calibration
Dial in the exact 740-750mm end-stop during initial machine commissioning to achieve precise positioning without machining custom spacers.
Product Changeover
Quickly trim the rear stroke by up to 10mm to accommodate slightly different package sizes on a packaging line.
Long-Stroke Forming
Leverage the 2513N push force at 0.5 MPa for heavy forming tasks while retaining the ability to fine-tune the retraction point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-10 the Right Cylinder?
Choose this 80mm bore when an application requires substantial thrust, such as 2513N push at 0.5 MPa, but demands precise end-position tuning that a fixed SAI cylinder cannot provide. If your force requirements are lower, stepping down to a 63mm bore yields 1559N push force, whereas stepping up to a 100mm bore provides 3927N. Because the 750mm stroke is lengthy, an external guide is recommended to prevent excessive side-loading on the rod.
This adjustable model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without continuous air pressure, a standard SAIJ is insufficient as the adjuster is only a stop; consider an external rod lock or the AirTAC SAIL lock variant instead.
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 SAIJ80AX750-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the nominal 750mm stroke by up to 10mm, resulting in a 740-750mm usable travel window. It sets the end position but does not hold the load without live air.
