Airtac SAU Standard Air Cylinder SAU80X145
The AirTAC Airtac SAU Standard Air Cylinder SAU80X145 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 145mm 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 SAU80X145
The AirTAC SAU80X145 is a double-acting profile-type cylinder with a 145 mm stroke. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, utilizing a 3/8 inch air port and an M20x1.5 rod thread.
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. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensor switches. If your environment exceeds the standard -20 to +70 C range, you can opt for Viton H seals to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X145 Is Used
Injection Mold Clamping
Provides robust 2513 N push force to secure mid-sized injection mold halves, leveraging the compact profile length to fit within tight press enclosures.
Pallet Stopper Gate
Acts as a heavy-duty stopping gate on roller conveyors, safely arresting pallets weighing up to 128 kg in vertical lift scenarios without requiring excessive axial space.
Stamping Press Feed
Drives heavy metal blanks into a stamping press, utilizing the 145 mm stroke and M20x1.5 rod to cycle rapidly at speeds between 30 and 800 mm/s.
Is the Airtac SAU Standard Air Cylinder SAU80X145 the Right Cylinder?
When sizing this 80 mm bore, compare it to its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. This SAU80X145 model shares mounting accessories with the AirTAC SC series, including LB foot brackets, FA/FB flanges, and CA/CB clevises. The 145 mm stroke is well below the 300 mm threshold, so side-load concerns are minimal.
Remember that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The adjustable 28 mm air cushions at both ends only decelerate the piston near stroke end to prevent impact, acting as a shock absorber rather than a brake. To suspend a load securely during an outage, integrate 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 SAU80X145 FAQ
The SAU80X145 features a 3/8 inch air port and generates 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.
It is not an ISO 15552 cylinder, so you must use AirTAC SC-series mounting accessories like LB, FA, FB, CA, or CB brackets. Additionally, because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
