About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100S
The AirTAC SAIJ80X165-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 165 mm nominal stroke that can be fine-tuned down by up to 100 mm, providing a usable travel window of 65 to 165 mm. This wide adjustment band is ideal for dialing in exact retract end-positions during commissioning without swapping hardware. The bore delivers 3518 N of push force at 0.7 MPa.
This unit includes a magnet for position sensing and uses a standard carbon steel rod with a PT tapered port thread. It retains the standard extruded aluminum barrel with sensor grooves on both sides for flexible switch mounting. The rear screw acts purely as a travel stop for deceleration alongside the variable air cushions, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100S Is Used
Product Changeover
Dial in the retract position by up to 100 mm when switching product sizes on a packaging line, avoiding the need to physically swap cylinders or add external stopper blocks.
Commissioning Calibration
Fine-tune the exact end-of-stroke position during machine setup to perfect a pressing or holding operation within the 65 to 165 mm travel window.
Variable End Stops
Provide a flexible retraction limit for automated assemblies where the required stroke length might vary slightly between different production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, such as 3518 N push force at 0.7 MPa, but with highly variable end-stop requirements. If you need less force, stepping down to a 63 mm bore yields 2182 N at 0.7 MPa. Selecting this adjustable SAIJ over a fixed-stroke SAI is advantageous for machine setups that undergo frequent product changeovers, as the 100 mm adjustment window allows rapid reconfiguration of the retract position. To replace an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, PT port threads, and desired mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ80X165-100S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides 3518 N of push force and 2268 N of pull force. It can reach a maximum push force of 4523 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the 165 mm nominal length, creating a 65 to 165 mm travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
