About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-50S
The AirTAC SAIJ80X165-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 115 to 165 mm. Delivering 2513 N of push force at 0.5 MPa, it is built with a carbon steel rod and a PT tapered port. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors.
This adjustable-stroke model allows you to fine-tune the retract end position during commissioning without swapping out the entire cylinder. It features an extruded aluminum barrel with sensor grooves on both sides and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw functions strictly as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-50S Is Used
Product Changeovers
Dial in the exact 115 to 165 mm end-stop during format size changes on packaging lines without adding external mechanical stops.
Machine Setup
Fine-tune the retract position at commissioning to achieve precise alignment, utilizing the 2513 N push force for rigid positioning.
Variable End Stops
Adjust the rear travel stop on the fly for automated assemblies requiring multiple stroke lengths from a single cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-50S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial thrust, such as 2513 N push at 0.5 MPa, alongside flexible end-position tuning. If your setup demands less force, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa. Conversely, heavier loads might require the 100 mm bore at 3927 N. The adjustable 115 to 165 mm window is perfect for product-size changeovers on a line, offering versatility that a fixed-stroke SAI cylinder cannot match.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, 50 mm adjustment, PT port thread, and -S magnet requirement. Because the 165 mm stroke is below the 300 mm threshold, external side-load guides are less critical, but the 25 mm rod and M20x1.5 thread still provide robust resistance to minor deflection. Remember that the rear adjuster is a stop, not a brake; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80X165-50S 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.
The rear adjuster screw allows you to shorten the nominal 165 mm stroke by up to 50 mm, creating a usable travel window of 115 to 165 mm. It acts as a mechanical stop for end-position tuning and does not lock the load without air pressure.
