Airtac SAU Standard Air Cylinder SAU80X850
The AirTAC Airtac SAU Standard Air Cylinder SAU80X850 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 850mm 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 SAU Standard Air Cylinder SAU80X850
The AirTAC SAU80X850 is a double-acting profile-type cylinder featuring an extruded aluminum barrel that is notably shorter than an ISO 15552 unit of the same bore. It operates at 0.15-1.0 MPa and generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The 3/8" port and M20x1.5 rod thread handle robust pneumatic flow, while the 28 mm adjustable air cushions at both ends decelerate the piston smoothly.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For real-world sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction. Vertically, it lifts about 128 kg with a 2:1 safety margin. You can also specify Viton H seals to push the operating temperature range up to 150 C for hot environments.

Where the Airtac SAU Standard Air Cylinder SAU80X850 Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between machining stations, utilizing the 2513 N push force to overcome initial friction without stalling.
Vertical Crate Lifter
Elevates packaging crates in a distribution hub, safely lifting loads up to 128 kg when oriented vertically with a 2:1 safety margin.
Injection Mold Ejection
Drives a long-stroke ejection panel on a large plastic molding machine, requiring the 850 mm travel to fully clear deep mold cavities.
Is the Airtac SAU Standard Air Cylinder SAU80X850 the Right Cylinder?
When sizing this 80 mm bore, compare it to its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. This SAU80X850 fits squarely in the heavy-duty range. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis brackets. Because this specific SKU has no -S suffix, it lacks the internal magnet required for position sensing.
At an 850 mm stroke, the 25 mm rod is susceptible to bending under lateral stress. You must use external guide rails to prevent side-loading and ensure the load travels purely linearly. Furthermore, standard air cushions only decelerate the piston near the end of travel; they do not act as a brake. If the machine loses air, the piston will drift, so install an external rod lock or pilot-operated check valve to suspend heavy loads safely.
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 SAU Standard Air Cylinder SAU80X850 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa it pushes 3518 N, and at 0.9 MPa it pushes 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It features a 3/8" port, a 25 mm rod, and operates at speeds between 30-800 mm/s.
It is strictly compatible with AirTAC SC-series mounting accessories like LB, FA, and CA brackets, not ISO 15552 hardware. Additionally, this specific SAU80X850 SKU lacks the internal magnet, so it cannot support CMSG, DMSG, or EMSG magnetic sensors.
