About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40
The AirTAC SAIJ80X110-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 110 mm stroke that can be mechanically dialed back by up to 40 mm, yielding a precise 70-110 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, this extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position feedback.
The integrated rear stopper allows technicians to fine-tune the retract end-position during commissioning without adding external stops. It uses a carbon steel piston rod with an M20x1.5 thread, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments. Note that the rear adjuster functions strictly as a travel stop, not a lock, and cannot hold loads without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40 Is Used
Machine Commissioning
Dial in the exact retract distance within the 70-110 mm window during initial startup to perfect tooling alignment without machining new spacers.
Product Changeover
Quickly adapt the end-stop position on a packaging line when switching to a different package size, utilizing the 40 mm adjustment range.
Variable End Positioning
Provide adjustable mechanical stops for assembly stations where the effective stroke needs fine-tuning based on component tolerances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40 the Right Cylinder?
Select this 80 mm bore cylinder when an application requires moderate thrust combined with variable end-stop positioning. If your setup needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa; if more power is required, a 100 mm bore provides 3927 N. Choose this adjustable SAIJ variant over a fixed SAI model when you anticipate product changeovers or need to trim the stroke by up to 40 mm during machine setup. For load-holding without continuous air pressure, consider an external rod lock or the AirTAC SAIL and BSAI series instead of relying on the rear stopper.
Because this unit features a 110 mm stroke, side-load risks are relatively low, but the load should still remain guided to protect the M20x1.5 carbon steel rod. This SKU is configured with PT tapered ports and no internal magnet. When matching ISO 15552 replacements, verify the 80 mm bore, 110 mm nominal stroke, 40 mm adjustment range, PT port thread, and the specific mounting hardware.
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 SAIJ80X110-40 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
A rear external screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its 110 mm nominal length down to 70 mm. The adjuster sets the travel end but does not lock the load without live air pressure.
