Airtac SAU Standard Air Cylinder SAU80X90S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X90S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 90mm 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 SAU80X90S
The AirTAC SAU80X90S is a double-acting profile-type cylinder engineered with a 90 mm stroke and an 80 mm bore. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa. Designed with an extruded aluminum barrel, this unit is notably shorter and more compact than an ISO 15552 cylinder of the same bore, providing a distinct space advantage in tight machinery layouts. It features a 3/8" air port, an M20x1.5 rod thread, and a 25 mm piston rod.
Because this SKU includes the -S suffix, it has a built-in piston magnet ready for CMSG, DMSG, or EMSG electronic switches seated directly in the profile groove. For practical sizing, plan for a safe working load of about 1508 N (60% of the 0.5 MPa push rating) to account for seal friction. In a vertical lift scenario with a 2:1 safety margin, it can lift roughly 128 kg. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X90S Is Used
Heavy-Duty Stamping Press
Drives a 120 kg stamping die with steady force, utilizing the 90 mm stroke to form metal components in automated fabrication lines.
Pallet Dispenser Gate
Actuates a heavy diverter gate in a packaging conveyor, relying on the compact profile to fit within restrictive conveyor frame clearances.
Injection Mold Ejection
Pushes finished molded parts out of a hot zone, pairing the 1508 N safe working load with Viton H seals to withstand ambient radiant heat.
Is the Airtac SAU Standard Air Cylinder SAU80X90S the Right Cylinder?
When sizing this 80 mm bore, compare it against adjacent options: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. The 90 mm stroke sits well within the 1500 mm maximum standard limit, keeping the assembly rigid without requiring extended guide rails. Mount this cylinder using AirTAC SC-series accessories, such as LB foot brackets, FA/FB flanges, or CA/CB clevises. Keep in mind that the adjustable air cushion at both ends only decelerates the piston near the stroke limits; it will not hold a load vertically if air pressure drops. For suspended loads, install an external rod lock or a pilot-operated check valve to prevent drift.
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 SAU80X90S FAQ
This 80 mm bore cylinder features a 3/8" air port and generates 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder. It is a compact profile cylinder that shares mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). The -S suffix means it includes a magnet for CMSG/DMSG/EMSG sensors.
