Airtac SAU Standard Air Cylinder SAU80X650
The AirTAC Airtac SAU Standard Air Cylinder SAU80X650 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 650mm 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 SAU80X650
The AirTAC SAU80X650 is a double-acting profile-type standard cylinder engineered for heavy-duty automation. Featuring an extruded aluminum barrel, it provides a significant space advantage by being shorter than an ISO 15552 cylinder of the same bore. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, utilizing a 25 mm piston rod and a 3/8" air port.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The adjustable air cushions at both ends decelerate the piston near stroke end, and a high-temperature Viton H seal option extends the operating range up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X650 Is Used
Automotive Panel Stamping
Drives heavy press dies over the 650 mm travel, utilizing the 2513 N push force to form steel body panels reliably.
Pallet Diverting Gate
Actuates large routing gates on heavy-duty packaging lines, where the compact profile saves valuable floor space.
Vertical Lift Station
Elevates material totes weighing up to 128 kg, relying on the robust 80 mm bore to handle substantial vertical loads.
Is the Airtac SAU Standard Air Cylinder SAU80X650 the Right Cylinder?
When sizing this 80 mm bore, evaluate the neighboring options: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. This SAU80X650 model lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. You can utilize AirTAC SC-series mounting accessories, such as LB foot or FA flange brackets, for installation.
Because this model features a 650 mm stroke, it is highly susceptible to side-load and rod-bending forces; always incorporate an external guide to support the load. Furthermore, a standard cylinder drifts when air is lost or a valve is centered—the cushion only decelerates movement, it does not lock the load. To maintain position, integrate an external rod lock or a pilot-operated check valve.
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 SAU80X650 FAQ
The SAU80X650 features a 3/8" air port and generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force is 3518 N, and the theoretical maximum force is 513 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, so use SC-series LB, FA, or CA brackets. This specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic sensors.
