Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 110mm 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 SAUJ80X110-40S
The AirTAC SAUJ80X110-40S is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you trim the 110 mm nominal stroke by up to 40 mm, yielding a usable 70-110 mm window. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port, an M20x1.5 rod thread, and 28 mm adjustable air cushions.
This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. The computed safe working load is roughly 1508 N, translating to a 128 kg vertical lift with a 2:1 margin. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40S Is Used
Press Fit Dialing
Fine-tune the pressing depth of bearings on an assembly line by adjusting the extend stroke up to 40 mm without swapping the cylinder.
Variable Carton Flaps
Accommodate different box heights on a packaging conveyor by turning the external stop screw to set the exact flap folding position.
Adjustable Stops
Act as a movable end-stop for incoming pallets, allowing operators to quickly reposition the contact point for various load dimensions.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40S the Right Cylinder?
When sizing this unit, compare it against the neighboring 63 mm bore (2182 N push at 0.7 MPa) and the 100 mm bore (5497 N push at 0.7 MPa) to match your force requirements. Choose the SAUJ80X110-40S over a fixed SAU cylinder when your machine design requires field tuning of the extend end position, saving you from buying multiple cylinders for prototype iterations. Basic, FA flange, and LB foot mountings are available, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic or reed position sensing. Because the 110 mm stroke is relatively short, side-load stress is minimal, but for any stroke over 300 mm you should utilize external guide rails to prevent rod binding.
Quick checklist

- ✓ 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 SAUJ80X110-40S FAQ
At 0.5 MPa this 80 mm bore cylinder pushes 2513 N and pulls 2268 N. Push force is 3518 N at 0.7 MPa, 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The 110 mm nominal extend stroke can be shortened by up to 40 mm via the stop screw, giving a 70-110 mm working range.
The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG sensors. The external stop screw sets the extend end position but is not a load lock; the air cushions only decelerate the piston. Because the cylinder drifts without live air, use an external rod lock or pilot-operated check valve to hold a suspended load.
