Airtac SAUD Double Rod Cylinder SAUD80X275
The AirTAC SAUD Double Rod Cylinder SAUD80X275 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 275mm 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 SAUD Double Rod Cylinder SAUD80X275
The AirTAC SAUD80X275 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends, meaning push and pull forces are equal at 2268 N each way at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port and M20x1.5 rod threads.
Because both faces use the rod-side area, output is symmetrical. The 28 mm adjustable air cushions at each end decelerate the piston near stroke end. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high heat, Viton H seals raise the limit to 150 C.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD80X275 Is Used
Synchronized Transfer
Drives two parallel conveyor stops simultaneously from one piston, keeping material flow perfectly timed without twisting.
Twin Tool Head
Mounts a forming tool on the front rod and a return cam on the back rod to cycle opposing stamping dies in one motion.
Balanced Lowering
Lowers a 116 kg platen vertically with equal push and pull force, preventing drift during directional changes.
Is the Airtac SAUD Double Rod Cylinder SAUD80X275 the Right Cylinder?
Choose this 80 mm bore delivering 2268 N both ways when you need anti-rotation guidance or twin tooling. Sizing down, the 63 mm bore gives 1402 N both ways. Sizing up, the 100 mm bore provides 3681 N. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. At 275 mm stroke, ensure external guides carry side loads to prevent binding. This non-magnet version cannot host switches; for sensing select an -S SKU.
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 SAUD Double Rod Cylinder SAUD80X275 FAQ
Force is equal in both directions because of the double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port feeds both chambers equally.
No. The air cushions only decelerate the piston near the stroke ends; they do not act as a brake. If air is lost, the load will drift. Use an external rod lock or pilot-operated check valve for secure load holding.
