Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 1000mm 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 SAUJ80X1000-40S
The AirTAC SAUJ80X1000-40S is a double-acting, single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke on-site by up to 40 mm. You get a usable extend range of 960-1000 mm from the 1000 mm nominal 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 at each end. This -S SKU includes a piston magnet for CMSG, DMSG, or EMSG sensors.
In the 80 mm bore class, this cylinder delivers a push of 2513 N and a pull of 2268 N at 0.5 MPa, reaching 4523 N at 0.9 MPa. A practical computed insight: the safe working load is roughly 1508 N (about 60 percent of the 0.5 MPa push force), and it can vertically lift around 128 kg with a 2:1 safety margin. You can also specify Basic, FA flange, or LB foot mounting, and select Viton H seals for high-temperature environments up to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40S Is Used
Divert Gate Positioning
Trimming the extend stroke by up to 40 mm on-site lets you perfectly set a diverter gate's reach without machining new hard stops.
Variable Height Pallet Stops
Dial in the exact stopping point for varying pallet heights on a 1000 mm travel line, using the external screw to fine-tune the endpoint.
Press Pin Depth Tuning
Adjust the extend end position precisely to accommodate different pin insertion depths while maintaining 2513 N of push force.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40S the Right Cylinder?
When sizing this 80 mm bore, look both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires minor on-site extend length tuning without buying a new cylinder. The 40 mm adjust window is ideal for dialing in exact end positions. Mounting is compatible with the AirTAC SC series via Basic, FA, or LB styles. Because this model carries the -S suffix, you can directly mount CMSG, DMSG, or EMSG sensors. Since the stroke is 1000 mm, you must use external guides to prevent rod bending and manage side loads.
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 SAUJ80X1000-40S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull, reaching 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The 1000 mm nominal extend stroke can be shortened by up to 40 mm via the external stop screw, yielding a usable range of 960-1000 mm. The 3/8" port and 28 mm cushions are fixed for this 80 mm bore.
The external stop screw mechanically limits the piston's extend travel, letting you set the exact end position on-site. This stop sets the endpoint but is not a load lock; a plain cylinder drifts on air loss and the cushion only decelerates, so use an external rod lock for held loads. The -S suffix means a built-in piston magnet is present for direct mounting of CMSG, DMSG, or EMSG reed or electronic sensors.
