Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40 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 SAUJ80X110-40
The AirTAC SAUJ80X110-40 is a double-acting single-rod profile cylinder built for on-site stroke adjustment. An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable working range of 70-110 mm from the 110 mm maximum. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. For design sizing, a safe working load is roughly 1508 N (about 60% of the 0.5 MPa push force), translating to a 128 kg vertical lift with a 2:1 safety margin. Basic, FA, and LB mountings are available. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40 Is Used
Press Fit Depth Tuning
Dial in exact insertion depth on an assembly line. The 40 mm stop screw window lets operators compensate for material thickness variations without changing the actuator.
Variable Length Diverter
Adjust the extend stroke on a sorting gate to handle different package sizes. Shorten the travel by up to 40 mm on-site to perfectly match carton dimensions.
Adjustable Sealing Head
Fine-tune the down-stroke of a sealing mechanism. The external screw allows quick changes to the 110 mm nominal stroke for varying product heights.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-40 the Right Cylinder?
When sizing this actuator, look at both neighboring bores: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the SAUJ80X110-40 when your machine needs precise extend-end positioning without buying multiple fixed-length SAU cylinders. The 40 mm adjust window is ideal for dialing in exact travel on-site. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because this non-magnetic SKU cannot accept position sensors, you must verify travel externally. For strokes at or above 300 mm, always use external guides to prevent side-load wear. Operating speed spans 30-800 mm/s.

- ✓ 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 SAUJ80X110-40 FAQ
This 80 mm bore cylinder delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The theoretical max force is 513 kgf at 1.0 MPa. The nominal 110 mm extend stroke can be shortened by up to 40 mm via the external stop screw, yielding a usable 70-110 mm range. The 3/8" port and 28 mm cushions ensure smooth deceleration.
No. The external stop screw only sets the end position; it is not a load lock. If air is lost or the valve is centered, the piston will drift. The air cushions only decelerate the moving load near the stroke end. To safely hold a load, you must add an external rod lock or a pilot-operated check valve.
