Airtac SAU Standard Air Cylinder SAU80X165
The AirTAC Airtac SAU Standard Air Cylinder SAU80X165 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 165mm 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 SAU80X165
The AirTAC SAU80X165 is a double-acting profile-type cylinder featuring a 165 mm stroke and an extruded aluminum barrel. It provides a robust 2513 N push force at 0.5 MPa. Designed with a 3/8" port and an M20x1.5 rod thread, it operates at speeds of 30-800 mm/s. The integrated profile barrel incorporates an adjustable 28 mm air cushion at both ends to decelerate the piston near stroke limits.
Because this unit lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For real-world sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction. In a vertical lift scenario with a 2:1 safety margin, it lifts about 128 kg. If your environment exceeds the standard -20 to +70 C range, specify the Viton H high-temperature seal option for up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X165 Is Used
Injection Mold Clamping
Provides the 2513 N push force required to secure mid-sized injection mold halves within a compact machinery footprint.
Pallet Dispenser Gates
Actuates heavy pneumatic gating mechanisms on automated palletizing lines where the 128 kg vertical lift capacity excels.
Heavy Duty Press Ejection
Ejects dense formed parts from hydraulic presses, utilizing the 28 mm adjustable air cushion to prevent end-of-stroke impact damage.
Is the Airtac SAU Standard Air Cylinder SAU80X165 the Right Cylinder?
When sizing this 80 mm bore, compare it against adjacent options: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. This SAU80X165 offers a middle ground for mid-heavy machinery. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. Since this specific SKU lacks a magnet, position sensing is unavailable.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The adjustable cushion only slows the piston at the end of travel and does not function as a braking device. To suspend a load safely during an air loss event, 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 SAU80X165 FAQ
The SAU80X165 features a 3/8" port and generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and at 0.9 MPa it pushes 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
You cannot use ISO 15552 brackets; mounting compatibility is strictly with the AirTAC SC-series accessories (LB, FA, FB, CA, CB). Additionally, because this SAU80X165 SKU lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG magnetic switches.
