About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX275-10
The AirTAC SAIJ80X275-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 265-275 mm window. Delivering a robust 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa), it is built to handle demanding industrial positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This specific SKU is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads (G3/8). The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning without adding external stops; it is not a lock and will not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX275-10 Is Used
Machine Changeover
Dial in the exact 265 to 275 mm end position during product size changes without swapping out the entire cylinder or reworking the fixture.
End-Stop Tuning
Use the rear 10 mm adjustment screw to precisely set the retract end-position during commissioning, absorbing mechanical tolerances in the assembly.
Heavy Material Handling
Leverage the 2513 N push force at 0.5 MPa to move heavy pallets or chassis components while fine-tuning the final stopping point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX275-10 the Right Cylinder?
Choose this 80 mm bore unit when an application requires heavy thrust but also demands precise end-position tuning during machine setup or product changeover. If you need slightly less force, stepping down to a 63 mm bore yields 1559 N of push at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. Because the 275 mm stroke exceeds 300 mm is not the case here, but always ensure adequate guiding for long unsupported loads to prevent rod side-loading damage.
Select the adjustable SAIJ over a fixed-stroke SAI when you need a built-in mechanical stop to trim up to 10 mm off the nominal travel. Remember that neither the rear adjuster nor the variable air cushions at both ends will hold a load safely without continuous air pressure; for fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI series cylinders. This model is dimensionally interchangeable with ISO 15552 cylinders and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80AX275-10 FAQ
The rear adjuster screw lets you shorten the nominal 275 mm stroke by up to 10 mm, creating a usable travel window of 265 to 275 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 513 kgf (approximately 5031 N).
