About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10
The AirTAC SAIJ80X225-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, making it suitable for heavy-duty positioning. The integrated adjuster provides a usable travel window of 215-225 mm, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping hardware.
This extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a G3/8 port and a 25mm carbon steel rod with an M20x1.5 thread. The rear screw acts purely as a travel stop for end-position tuning and is not a locking device, meaning live air is required to hold the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10 Is Used
Product Changeovers
Dial in the 215-225mm travel window during format changes to accommodate different product lengths without changing the cylinder.
Machine Setup
Fine-tune the final retract position during commissioning to align heavy tooling precisely, preventing hard mechanical crashes.
Variable End Stops
Establish exact end-of-stroke positions for repetitive heavy-duty tasks where a fixed 225mm stroke leaves no room for mechanical trim.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10 the Right Cylinder?
Choose this 80mm bore when a 50mm bore (982N push at 0.5 MPa) is insufficient but a 100mm bore (3927N) would be excessive. The adjustable stroke is ideal for product changeovers on a line where exact end-stops vary slightly by part size, eliminating the need to bolt on external stops. Because the 225mm stroke is under 300mm, side-load stress is moderate, but the 25mm rod still requires external guiding for heavy lateral loads. For drop-load prevention without air pressure, select a SAIL or BSAI model instead of relying on the adjuster. To match this ISO 15552 cylinder, confirm the 225mm stroke, 10mm adjustment, PT port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SAIJ80X225-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw lets you shorten the nominal 225mm stroke by up to 10mm, creating a 215-225mm travel window. It functions as a mechanical stop for position tuning and does not lock the load without live air pressure.
