Airtac SAU Standard Air Cylinder SAU80X120
The AirTAC Airtac SAU Standard Air Cylinder SAU80X120 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 120mm 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 SAU80X120
The AirTAC SAU80X120 is a double-acting profile-type cylinder featuring a 120 mm stroke and an extruded aluminum barrel. It is engineered to be noticeably shorter than an ISO 15552 cylinder of the same 80 mm bore, delivering a space-saving footprint for tight machinery. It provides 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 piston rod.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa, accounting for seal friction and smooth travel. In vertical lift applications, this translates to lifting about 128 kg with a 2:1 safety margin. This SKU does not include a magnet (-S), meaning it cannot support CMSG, DMSG, or EMSG magnetic switches. If sensing is required, select an -S variant. For high-temperature environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAU Standard Air Cylinder SAU80X120 Is Used
Injection Mold Clamping
Provides 2513 N of push force at 0.5 MPa to secure mid-sized injection mold halves, utilizing the compact profile to fit within tight clamping stations.
Heavy Package Diverting
Deploys a 120 mm stroke to push heavy cartons off a main conveyor line, safely handling loads up to 1508 N without exceeding operational limits.
Pallet Stopper Gate
Acts as a robust pneumatic stopper in pallet flow systems, absorbing impact via the 28 mm adjustable air cushion while holding back loads up to 128 kg vertically.
Is the Airtac SAU Standard Air Cylinder SAU80X120 the Right Cylinder?
When sizing this model, compare it against neighboring bores: the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the 80 mm bore when your load demands more power than the 63 mm can deliver but you want to retain a more compact frame than the 100 mm. This cylinder shares its mounting accessories—such as LB foot, FA/FB flange, and CA/CB clevis—with the AirTAC SC series. Note that a standard SAU cylinder will drift if air pressure is lost or the valve is centered; the adjustable air cushion only decelerates the piston near the stroke ends and does not function as a locking brake. To maintain a vertical load safely, install 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 SAU80X120 FAQ
The SAU80X120 features a 3/8" port and delivers 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.
This cylinder is shorter than an ISO 15552 unit but is not dimensionally interchangeable with ISO standards; it shares mounting accessories exclusively with the AirTAC SC series (LB, FA, FB, CA, CB). Additionally, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
