About the Airtac SAU Standard Air Cylinder SAU80X130
The AirTAC SAU80X130 is a double-acting profile-type cylinder with an 80 mm bore and 130 mm stroke. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers 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. This translates to lifting about 128 kg vertically with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 0-150 C for high-temperature environments.

Where the Airtac SAU Standard Air Cylinder SAU80X130 Is Used
Press Fit Assembly
Drives bearings into housings on an automated line, utilizing the 2513 N push force at 0.5 MPa to seat heavy components accurately.
Pallet Handling
Pushes loaded pallets sideways onto a secondary conveyor, where the compact profile length prevents interference with adjacent guarding.
Carton Sealing
Actuates heavy sealing heads against large industrial cartons, relying on the 28 mm adjustable air cushions to prevent end-of-stroke impact.
Is the Airtac SAU Standard Air Cylinder SAU80X130 the Right Cylinder?
When sizing this 80 mm bore model, compare it to its neighbors: a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. This SAU80X130 strikes a balance for medium-heavy loads. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches; you will need to select an -S variant if position sensing is required.
Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centered, as the piston will drift. The adjustable 28 mm air cushions only decelerate the piston near the stroke ends and do not function as a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Mounting is simplified via AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets.
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 SAU80X130 FAQ
The SAU80X130 features a 3/8" port and an M20x1.5 rod thread. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, a push force of 3518 N at 0.7 MPa, and a theoretical maximum force of 513 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, accepting LB, FA, FB, CA, and CB accessories. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
