About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100S
The AirTAC SAIJ80X180-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 25 mm carbon steel rod and delivers 2513 N of push force at 0.5 MPa, making it a robust choice for medium-to-heavy pneumatic tasks. An integrated magnet allows position detection via AirTAC CMSE reed or DMSE electronic sensors.
This specific SKU provides a nominal 180 mm stroke with a massive 100 mm adjustment range, creating an 80-180 mm usable travel window. The rear stopper screw lets you dial back the retract position by up to 100 mm during commissioning or product changeovers without swapping the cylinder. It utilizes a PT tapered port thread and includes adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100S Is Used
Product Changeover
Rapidly reconfigure the retract distance from 180 mm down to 80 mm on packaging lines handling varying box sizes, eliminating the need for mechanical spacer changes.
End-Position Tuning
Fine-tune the exact bottom-out point during machine commissioning to perfect a pressing or forming operation without disassembling the fixture.
Adjustable Ejection
Control the ejection stroke length on an assembly line to safely push parts of different heights into a chute without over-traveling.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial force—delivering 2513 N push and 2268 N pull at 0.5 MPa—and highly variable end-stop positioning. If you need less force, stepping down to a 63 mm bore yields 1559 N push force, whereas a 100 mm bore provides 3927 N for heavier loads. The wide 80-180 mm travel window makes the SAIJ80X180-100-S ideal for machines processing multiple product sizes, replacing the need to inventory several fixed-stroke SAI cylinders.
Because the 180 mm stroke is under the 300 mm side-load threshold, the 25 mm rod handles standard loads well, though external guides remain recommended for heavy lateral forces. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder will not hold its load without live air. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ80X180-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N. The standard operating speed range is 30-800 mm/s.
The rear adjuster acts as an external stopper that lets you mechanically shorten the effective stroke from 180 mm down to as little as 80 mm, creating an 80-180 mm travel window. It sets the retract end position but does not lock the load without continuous air pressure.
