Airtac SAU Standard Air Cylinder SAU80X50
The AirTAC SAU Standard Air Cylinder SAU80X50 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 SAU80X50
The AirTAC SAU80X50 is a double-acting profile-type cylinder with a 50 mm stroke. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a robust 2513 N of push force at 0.5 MPa. With a 3/8" port and a 25 mm rod, it handles heavy loads efficiently.
The standard TPU seals operate from -20 to +70 C, while a Viton H option extends this to 150 C. Note this specific SKU lacks the -S magnet, so it cannot host CMSG or DMSG sensors.

Where the Airtac SAU Standard Air Cylinder SAU80X50 Is Used
Injection Mold Clamping
Provides 2513 N of clamping force at 0.5 MPa to secure medium-sized injection mold halves during material injection.
Pallet Stopper Gate
Acts as a heavy-duty stop gate on conveyor lines, using its compact 50 mm stroke to halt loaded pallets on demand.
Is the Airtac SAU Standard Air Cylinder SAU80X50 the Right Cylinder?
When sizing, verify if the 63 mm bore (1559 N push at 0.5 MPa) is sufficient, or step up to the 100 mm bore (3927 N) for heavier demands. The 80 mm bore uses an M20x1.5 rod thread and 28 mm adjustable air cushions at both ends to absorb impact. Mounting relies on AirTAC SC-series accessories like LB foot or FA flange.
Because this is a double-acting cylinder, it will drift if air pressure drops or the valve centers; the end cushions only decelerate travel, they do not lock the piston. To suspend a vertical load safely, install an external pilot-operated check valve or a dedicated rod lock.
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 SAU80X50 FAQ
The SAU80X50 features a 3/8" port. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder; mounting accessories must match the AirTAC SC series (such as FA flange or CB clevis). Also, this SKU lacks the -S magnet, meaning it cannot accept CMSG or DMSG magnetic switches.
