Airtac SAU Standard Air Cylinder SAU80X450
The AirTAC Airtac SAU Standard Air Cylinder SAU80X450 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 450mm 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 SAU80X450
The AirTAC SAU80X450 is a double-acting profile-type standard cylinder featuring an extruded aluminum barrel and a 450 mm stroke. It is engineered to be more compact than an ISO 15552 cylinder of the same 80 mm bore, providing a distinct space advantage in tight machine layouts. Operating at 0.15-1.0 MPa, it delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. The unit utilizes a 3/8" port and a 25 mm carbon steel rod with an M20x1.5 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. In a vertical lift scenario with a 2:1 safety margin, this actuator can lift about 128 kg. This SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches. For high-temperature environments up to 150 C, you can specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU80X450 Is Used
Pallet Diversion
Pushes heavy pallets onto secondary packaging lines using its 2513 N push force at 0.5 MPa, fitting neatly into tight conveyor transfer zones.
Vertical Lift Gate
Raises and lowers a 120 kg mezzanine safety gate, leveraging the 450 mm stroke while benefiting from the shorter profile barrel dimensions.
Press Ejection
Ejects formed metal parts from a 80-ton stamping press, utilizing the 3/8" porting for rapid retraction and the M20x1.5 rod thread for tooling.
Is the Airtac SAU Standard Air Cylinder SAU80X450 the Right Cylinder?
When sizing this actuator, consider the neighboring bores: stepping down to the 63 mm bore yields 1559 N of push force at 0.5 MPa, while stepping up to the 100 mm bore provides 3927 N. This 80 mm model fits perfectly in the middle for medium-heavy loads. Because the 450 mm stroke is relatively long, external guides are recommended to prevent rod bending and mitigate side-load stresses during operation. Mounting is straightforward using AirTAC SC-series accessories, such as LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that a standard cylinder drifts if air pressure is lost or the valve is centered; the adjustable 28 mm air cushions only decelerate the piston near the stroke ends and do not function as a braking lock. To suspend a load securely, 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 SAU80X450 FAQ
This 80 mm bore cylinder features a 3/8" port and generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 3518 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
No, because this specific SKU does not include the -S magnet option, it cannot support CMSG, DMSG, or EMSG magnetic switches. You would need to specify an SAU80X450-S variant to utilize the sensor groove in the aluminum profile.
