Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10S 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 SAUJ80X85-10S
The AirTAC SAUJ80X85-10S is a double-acting single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 85 mm maximum stroke by up to 10 mm, yielding a 75-85 mm usable window to dial in your exact end position. It features a 3/8" port and a Ø25 mm piston rod.
This bore delivers robust force: 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. The computed safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix indicates a built-in magnet for CMSG/DMSG/EMSG switches.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10S Is Used
Press Fit Dialing
Fine-tune the 75-85 mm extend distance on-site to set precise insertion depths for bearing press operations without remachining stops.
Carton Flap Folding
Adjust the extend endpoint by up to 10 mm to accommodate varying package heights, ensuring flaps are tucked consistently.
Transfer Diverter Setup
Trim the actuator stroke on the line to perfectly align product diverters, using the magnetic piston for exact position confirmation.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X85-10S the Right Cylinder?
When sizing this 80 mm bore, compare it against the 63 mm and 100 mm options. The 63 mm yields 1559 N push at 0.5 MPa, while the 100 mm provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires minor 0-10 mm extend length tweaking without buying new hardware. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG sensors. For strokes over 300 mm, ensure external guide rails to prevent side-load wear.
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 SAUJ80X85-10S FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and a 513 kgf max at 1.0 MPa. The 85 mm nominal extend stroke can be shortened by up to 10 mm via the external stop screw, giving a 75-85 mm working range. It uses a 3/8" port and M20x1.5 rod thread.
The external stop screw physically limits the piston's extend travel, letting you trim the endpoint on-site. The -S suffix means a magnet is built into the piston, allowing CMSG, DMSG, or EMSG switches to detect position. Note that the stop screw sets the end position but does not lock the load; a separate rod lock or pilot check valve is needed to hold loads on air loss.
