Airtac SAU Standard Air Cylinder SAU80X140
The AirTAC Airtac SAU Standard Air Cylinder SAU80X140 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 140mm 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 SAU80X140
The AirTAC SAU80X140 is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It provides a shorter overall length than an ISO 15552 cylinder of the same bore, yielding a space advantage in tight machinery layouts. Operating at 0.5 MPa, it generates 2513 N of push force and 2268 N of pull force. The unit uses a 3/8" port and a 25 mm piston rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of roughly 1508 N, accounting for seal friction and smooth travel at 0.5 MPa. In vertical lifting scenarios with a 2:1 safety margin, this actuator lifts about 128 kg. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. You can select TPU seals for standard use or Viton H seals for high-temperature environments up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X140 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 machine frames.
Package Diverting
Extends 140 mm to push heavier cartons off a main conveyor line, handling the lateral force required to redirect goods efficiently.
Pallet Positioning
Shifts loaded pallets into alignment on a packaging conveyor, taking advantage of the 128 kg vertical lift capacity for vertical positioning tasks.
Is the Airtac SAU Standard Air Cylinder SAU80X140 the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores: the 63 mm option yields 1559 N push at 0.5 MPa, while the 100 mm version provides 3927 N. This 80 mm model fits applications requiring 2513 N. Since this SKU lacks a magnet, position sensing is unavailable unless you upgrade to an -S variant. Mounting hardware matches the AirTAC SC series, allowing the use of LB foot brackets, FA/FB flanges, or CA/CB clevises.
Remember that a standard cylinder does not hold its position if air pressure drops or the valve centers; the piston will drift. The adjustable 28 mm air cushions only decelerate the rod near the stroke ends and do not function as a braking mechanism. To suspend a load securely, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU80X140 FAQ
The SAU80X140 uses a 3/8" port and generates 2513 N push and 2268 N pull at 0.5 MPa. 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.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. For position feedback, you would need the -S variant. Mounting accessories remain compatible with the AirTAC SC series.
