Airtac SAU Standard Air Cylinder SAU80X210S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X210S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 210mm 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 SAU80X210S
The AirTAC SAU80X210S is a double-acting profile-type cylinder featuring an extruded aluminum barrel. It is purposefully built to be shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, offering a distinct spatial advantage in dense machinery layouts. It operates with a 2513 N push force at 0.5 MPa and utilizes a 3/8" port with an M20x1.5 rod thread.
For practical 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. The integrated -S piston magnet enables direct mounting of CMSG, DMSG, or EMSG switches in the profile groove, while the standard TPU seals handle temperatures from -20 to +70 C (a Viton H option extends this to 150 C).

Where the Airtac SAU Standard Air Cylinder SAU80X210S Is Used
Injection Mold Extraction
Provides the robust 2513 N push force needed to positively eject heavy molded parts from tight press cavities where overall cylinder length is restricted.
Pallet Diverting Arm
Drives a heavy-duty routing arm to shift loaded pallets between parallel conveyor lines, benefiting from the compact profile to fit within tight transfer zones.
Vertical Carton Lift
Lifts packaged goods weighing up to 128 kg in distribution centers, using the 210 mm stroke to raise items between tiered sorting platforms.
Is the Airtac SAU Standard Air Cylinder SAU80X210S 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, whereas a 100 mm bore provides 3927 N. This SAU80X210S sits comfortably in the middle for heavy-duty mid-range tasks. It shares mounting accessories with the AirTAC SC series, such as LB foot brackets, FA/FB flanges, and CA/CB clevises.
Because the 210 mm stroke is substantial, ensure external guide rails are used to prevent rod bending under heavy lateral loads. Furthermore, this standard cylinder will drift if air pressure is lost or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near stroke end. To suspend a load safely 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 SAU80X210S FAQ
This 80 mm bore cylinder uses a 3/8" port and an M20x1.5 rod thread. It generates 2513 N push and 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 dimensionally interchangeable with ISO 15552 brackets; you must use AirTAC SC-series accessories like LB, FA, FB, CA, or CB mounts. However, the -S magnet allows you to drop CMSG, DMSG, or EMSG sensors directly into the barrel's integrated groove.
