Airtac SAU Standard Air Cylinder SAU80X210
The AirTAC Airtac SAU Standard Air Cylinder SAU80X210 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 SAU80X210
The AirTAC SAU80X210 is a double-acting profile-type cylinder engineered with an extruded aluminum barrel that is physically shorter than an ISO 15552 unit of the same bore. Operating at 0.15-1.0 MPa, it moves a Ø25 mm hard-chrome rod through a 210 mm travel distance, delivering a robust 2513 N of push force at 0.5 MPa. The integrated profile barrel features a built-in sensor groove, though this specific SKU lacks the -S magnet and therefore cannot support CMSG, DMSG, or EMSG magnetic switches.
For practical sizing, plan your payload around a safe working load of roughly 1508 N at 0.5 MPa, accounting for seal friction and smooth travel dynamics. Alternatively, this translates to lifting about 128 kg vertically with a 2:1 safety margin, letting you match real part weights accurately. The unit utilizes a 3/8" port and M20x1.5 rod thread, while standard TPU seals handle temperatures from -20 to +70 C, with a Viton H option available for environments up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X210 Is Used
Injection Mold Extraction
Provides the 2513 N push force needed to positively eject dense plastic automotive interior panels from heavy tooling molds.
Palletized Goods Diversion
Drives heavy-duty pusher arms on packaging conveyors, utilizing the 210 mm stroke to redirect loaded pallets onto secondary spur lines.
Woodworking Press Clamping
Holds solid timber assemblies securely during adhesive curing, taking advantage of the compact profile length to fit within dense multi-station presses.
Is the Airtac SAU Standard Air Cylinder SAU80X210 the Right Cylinder?
When sizing this 80 mm bore, evaluate your neighboring options: a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. If your machine requires position feedback, you must select the -S magnet variant to activate sensor functionality. Mounting hardware is fully cross-compatible with the AirTAC SC series, allowing you to utilize LB foot brackets, FA/FB flanges, CA/CB clevises, or I/Y/F/U knuckles. At a 210 mm stroke, side-load risks are moderate, so ensure your guide mechanism absorbs lateral forces to prevent premature rod seal wear. Remember that standard air cushions only decelerate the piston near stroke end and do not function as a braking mechanism; if power drops, the rod drifts. To secure a vertical load safely during air loss, integrate an external rod lock or a pilot-operated check valve into your 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 SAU80X210 FAQ
This 80 mm bore model features a 3/8" port and delivers 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. It uses an M20x1.5 rod thread and has a 28 mm adjustable air cushion at both ends.
It is not an ISO 15552 cylinder, but its mounting accessories are fully compatible with the AirTAC SC series, including LB, FA, FB, CA, and CB brackets. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches; you must order the magnet-equipped version for position sensing.
