Airtac SAU Standard Air Cylinder SAU80X115
The AirTAC Airtac SAU Standard Air Cylinder SAU80X115 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 115mm 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 SAU80X115
The AirTAC SAU80X115 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space while delivering 2513 N of push force at 0.5 MPa. It operates at 30-800 mm/s and uses a 3/8 inch port with an M20x1.5 rod thread.
Because seal friction and smooth travel eat into theoretical ratings, plan for a safe working load of about 1508 N at 0.5 MPa. For vertical lifts, this translates to lifting roughly 128 kg with a 2:1 safety margin. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensor switches. If your environment exceeds 70 C, the Viton H high-temperature seal option extends operation to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X115 Is Used
Stamping Press Feed
Pushes heavy coil stock into a mechanical press, utilizing the 2513 N force at 0.5 MPa to overcome material friction during continuous feed cycles.
Pallet Dispenser Gate
Actuates a heavy loading bay gate, where the compact profile length prevents the cylinder from protruding into the forklift traffic lane.
Package Divert Arm
Drives a mechanical sorting arm on a high-speed conveyor belt, using the 115 mm stroke to rapidly push parcels onto an adjacent routing lane.
Is the Airtac SAU Standard Air Cylinder SAU80X115 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 SAU80X115 fits squarely for medium-heavy tasks. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis options. You can also use I, Y, F, or U rod knuckles.
Remember that a standard cylinder drifts when air is lost or a valve centers; the adjustable 28 mm air cushions only decelerate the piston near stroke end and do not act as a brake. For suspended or gravity-loaded applications, install an external rod lock or a pilot-operated check valve to hold the payload securely.
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 SAU80X115 FAQ
The 80 mm bore uses a 3/8 inch port. At 0.5 MPa it provides 2513 N push and 2268 N pull force. At 0.7 MPa the push force is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, so you must use AirTAC SC-series mounting accessories like LB, FA, or CA brackets. Additionally, this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic sensors.
