Airtac SAU Standard Air Cylinder SAU80X375
The AirTAC Airtac SAU Standard Air Cylinder SAU80X375 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 375mm 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 SAU80X375
The AirTAC SAU80X375 is a double-acting profile-type cylinder engineered with a 375 mm stroke and an extruded aluminum barrel. Because it is shorter than an ISO 15552 cylinder of the same bore, it saves valuable machine space while delivering substantial force. It provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, with a 3/8" port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction and smooth travel. In vertical lift scenarios, this translates to lifting about 128 kg with a 2:1 safety margin. The unit features adjustable air cushions at both ends to decelerate the piston, and because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches.

Where the Airtac SAU Standard Air Cylinder SAU80X375 Is Used
Automotive Panel Pressing
Applies 2513 N of push force at 0.5 MPa to form and stamp lightweight automotive body panels, utilizing the 375 mm stroke to clear large workpieces.
Heavy Package Diversion
Actuates a heavy-duty routing arm on a logistics conveyor, safely pushing 128 kg palletized goods using the 2:1 vertical lift margin.
Palletized Goods Lift
Raises stacked inventory between conveyor tiers, relying on the compact profile to fit within tight vertical transfer elevator frames.
Is the Airtac SAU Standard Air Cylinder SAU80X375 the Right Cylinder?
When sizing this 80 mm bore, compare it against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. This SAU80X375 fits perfectly in the middle for medium-heavy handling. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis options.
Because the 375 mm stroke is relatively long, you should use an external guide to prevent rod bending and absorb side loads. Remember that a standard cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near stroke end and does not act as a brake. For load holding, 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 SAU80X375 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. 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. It operates at 30-800 mm/s, uses a 3/8" port, and has an M20x1.5 rod thread.
It is not dimensionally interchangeable with ISO 15552 brackets; you must use AirTAC SC-series mounting accessories like LB, FA, FB, CA, or CB. Additionally, because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG magnetic switches.
