About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-50S
The AirTAC SAIJ80X160-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3518N push force at 0.7MPa, utilizing a 25mm carbon steel rod and G3/8 PT ports. The integrated -S magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic sensors.
This model provides a usable travel window of 110-160mm, allowing you to dial back the nominal 160mm stroke by up to 50mm. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable rear stopper lets you fine-tune end positions at commissioning without swapping out the cylinder.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-50S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point between 110 and 160mm during machine setup, eliminating the need for external mechanical stops.
Product Size Changeovers
Quickly adapt the cylinder stroke on packaging lines when processing different product sizes, keeping downtime to a minimum.
Assembly Press Positioning
Precisely set the lower travel limit for pressing operations, accommodating various component heights without changing the cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-50S the Right Cylinder?
Choose this 80mm bore when an application requires significant thrust, such as 4523N push force at 0.9MPa, but demands flexible end-stop positioning during product changeovers. If you need less force, the 63mm bore offers 2182N at 0.7MPa. For heavier loads, the 100mm bore provides 5497N at 0.7MPa.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series instead of the SAIJ. This cylinder uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ80X160-50S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm. This gives you a usable travel window between 110mm and 160mm, allowing fine-tuning of the end position without replacing the cylinder.
At an operating pressure of 0.7MPa, this 80mm bore cylinder generates 3518N of push force and 2268N of pull force. At 0.9MPa, the push force increases to 4523N.
