Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 85mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10
The AirTAC SAUJ80X85-10 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 10 mm, giving a usable extend range of 75-85 mm. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 25 mm rod, M20x1.5 rod thread, and a 3/8" port.
This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N push at 0.9 MPa. For sizing, a safe working load is roughly 1508 N (about 60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. Standard adjustable air cushions are 28 mm. Note this SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10 Is Used
Press Fit Dial
Needs field stroke tuning to set precise 75-85 mm insertion depths for varying bearing sizes without swapping the cylinder.
Transfer Diverter
Requires adjusting the extend endpoint by up to 10 mm on-site to perfectly align packages onto secondary conveyor lanes.
Carton Flap Folder
Demands minor extend stroke trims to accommodate different carton heights, ensuring flaps fold cleanly without crushing the box.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10 the Right Cylinder?
Size this 80 mm bore against the 63 mm and 100 mm options. The 63 mm yields 1559 N push at 0.5 MPa, while the 100 mm hits 3927 N; this SAUJ80X85-10 provides 2513 N. Choose the 10 mm adjust window when you need minor end-position tweaking rather than a massive stroke reduction. It is ideal when you want built-in mechanical tuning instead of buying a fixed SAU and fabricating an external stop. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this SKU has no -S magnet, position sensing is impossible. For this 85 mm stroke, side-loading is minimal, but for any stroke over 300 mm always use external guide rails.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10 FAQ
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa. The theoretical max is 513 kgf at 1.0 MPa. The external stop screw allows you to shorten the extend stroke by up to 10 mm, yielding a usable range of 75-85 mm. It uses a 3/8" port and 28 mm adjustable cushions.
No. A plain SAUJ does not hold a load without live air; the piston will drift and the 28 mm air cushion only decelerates near the end of travel. The external stop screw sets the end position but is not a load lock. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
