Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40 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 SAUJ80X1000-40
The AirTAC SAUJ80X1000-40 is a double-acting single-rod profile cylinder with a 1000 mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 40 mm, yielding a usable range of 960-1000 mm. The extruded aluminum profile 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 generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. A practical computed insight: the safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 128 kg with a 2:1 safety margin. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments beyond the standard -20 to +70 C range, Viton H seals extend operation to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40 Is Used
Divert Gate Tuning
Adjusts the extend stroke by up to 40 mm to perfectly set a diverter gate angle on-site without disassembling the pneumatic line.
Pallet Stop Positioning
Fine-tunes the physical stopping point for varying pallet sizes on a 1000 mm travel conveyor, ensuring precise 960-1000 mm placement.
Forming Press Depth
Trims the working stroke on a light forming press to accommodate different material thicknesses, preventing over-travel.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-40 the Right Cylinder?
When sizing this unit, compare it against the neighboring 63 mm bore, which provides 1559 N push at 0.5 MPa, and the larger 100 mm bore delivering 3927 N. Choose the SAUJ80X1000-40 over a fixed SAU cylinder when your assembly requires minor 0-40 mm end-position tweaks without buying new hardware. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this SKU has no -S suffix, magnetic sensing is impossible. At a 1000 mm stroke, you must use external guides to prevent rod bending and manage side loads. Remember the stop screw only sets the end position; it is not a load lock.
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 SAUJ80X1000-40 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N push and 2268 N pull force. Push force rises to 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 nominal 1000 mm extend stroke can be shortened by up to 40 mm via the external stop screw, giving a usable range of 960-1000 mm. The air port is 3/8 inch.
No, a plain cylinder drifts when air is lost or the valve is centered. The 28 mm adjustable air cushion only decelerates the piston near the end of stroke, and the external stop screw merely sets the end position; neither acts as a load lock or brake. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
