Airtac SAU Standard Air Cylinder SAU80X50S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X50S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 50mm 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 SAU80X50S
The AirTAC SAU80X50S is a double-acting profile-type cylinder with a 50 mm stroke and an 80 mm bore. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, providing a space advantage in tight machine layouts. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating on a 3/8" port with a 25 mm rod.
For real-world sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction and smooth travel. Vertically, this translates to lifting about 128 kg with a 2:1 safety margin. The included -S magnet enables direct mounting of CMSG, DMSG, or EMSG sensors in the profile groove, while the adjustable 28 mm air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAU Standard Air Cylinder SAU80X50S Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves within a compact machinery footprint.
Pallet Diverting
Delivers rapid 50 mm strokes to push heavy product pallets off a main conveyor line, utilizing the 3/8" port for high flow.
Heavy Crate Lifting
Lifts vertically loaded crates weighing up to roughly 128 kg using a 2:1 safety margin on the 0.5 MPa push force.
Is the Airtac SAU Standard Air Cylinder SAU80X50S the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, whereas a 100 mm bore provides 3927 N. This SAU80X50S fits perfectly when the 63 mm class is insufficient for moving heavy jigs. It shares mounting accessories with the AirTAC SC series, allowing you to use LB foot brackets, FA/FB flanges, or CA/CB clevises. Note that an air cushion only decelerates the piston near the stroke end; it does not act as a brake. Because a standard cylinder drifts when air is lost or a valve is centered, add an external rod lock or pilot-operated check valve if your application requires strict load holding.
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 SAU80X50S FAQ
The SAU80X50S features an 80 mm bore and a 3/8" air port. It generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, a push force of 3518 N at 0.7 MPa, and a theoretical maximum force of 513 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet. This allows you to install CMSG, DMSG, or EMSG reed or electronic switches directly into the sensor groove of the extruded aluminum profile barrel.
