About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-10
The AirTAC SAIJ80X180-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa, utilizing a PT-tapered G3/8 port and a 25mm carbon steel rod. By turning the rear screw, you can trim the effective travel within a 170-180mm window, providing precise end-position tuning without swapping out the entire unit.
This adjustable-stroke design excels during machine commissioning and product changeovers, allowing you to dial in the exact retract distance on the fly. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement. While the rear adjuster and variable air cushions safely decelerate the load at the travel end, note that this mechanism acts as a stop rather than a lock; it will not hold the load without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-10 Is Used
End-Stop Calibration
Dial in the exact 170-180mm retract distance during machine commissioning to meet tight positional tolerances without machining custom spacers.
Product Changeover
Quickly adjust the rear stopper screw on a packaging line to accommodate slightly different carton depths without changing the cylinder.
Assembly Pressing
Leverage the 2513N push force at 0.5 MPa to seat components, using the fine adjustment to prevent over-travel and damage to delicate parts.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-10 the Right Cylinder?
Choose this 80mm bore when an application requires more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but has spatial or budget constraints that prevent stepping up to a 100mm unit. The 10mm adjustment range is ideal for fine-tuning a 180mm stroke to meet tight positional tolerances during setup, eliminating the need to bolt on external stoppers or fabricate custom spacers.
To achieve a direct ISO 15552 replacement, match the 80mm bore, 180mm nominal stroke, G3/8 PT port, and the required mounting style. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Because this is a non-magnet variant, position sensing requires adding an external switch track or specifying a -S magnet model to utilize CMSE reed or DMSE electronic sensors. If true load-holding without live air is required, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ80X180-10 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 adjuster screw acts as an external stopper, allowing you to shorten the 180mm nominal stroke by up to 10mm. This creates a 170-180mm usable travel window for fine-tuning the end position during setup.
