Airtac SAU Standard Air Cylinder SAU80X1620S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X1620S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 1620mm 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 SAU80X1620S
The AirTAC SAU80X1620S is a double-acting profile-type cylinder featuring a 1620 mm stroke. Because the stroke exceeds the 1500 mm standard maximum for this bore, it is produced as a non-standard, made-to-order unit. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, delivering 2513 N of push force at 0.5 MPa through a 3/8" port.
For practical sizing, plan for a safe working load of about 1508 N, which accounts for seal friction during smooth travel. In a vertical lift scenario with a 2:1 safety margin, it lifts about 128 kg. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for position detection.

Where the Airtac SAU Standard Air Cylinder SAU80X1620S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1620 mm between machining centers, utilizing the 2513 N push force to overcome initial friction without stalling.
Vertical Parts Elevator
Lifts components weighing up to 128 kg to a second-tier assembly line, relying on the compact profile to minimize vertical machine footprint.
Large Door Actuation
Opens and closes heavy industrial oven doors, using the integrated magnet and DMSG sensors to confirm fully open and closed endpoints.
Is the Airtac SAU Standard Air Cylinder SAU80X1620S the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores: the 63 mm option yields 1559 N of push at 0.5 MPa, while the 100 mm version provides 3927 N. Choose the 80 mm bore when your application demands the 2513 N output and a 25 mm piston rod. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets.
Because this unit features a 1620 mm stroke, the extended rod is highly susceptible to bending under lateral stress; always incorporate an external guide rail to prevent side-loading damage. Furthermore, this cylinder relies on air pressure to maintain position. If air is lost or the valve is centered, the piston will drift, as the adjustable 28 mm air cushions only decelerate the piston near stroke ends rather than locking it. Install an external rod lock or pilot-operated check valve for secure load holding.
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 SAU80X1620S FAQ
At 0.5 MPa it provides 2513 N of push and 2268 N of pull force. At 0.7 MPa the push force is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It operates at 30-800 mm/s, uses a 3/8" port, and features a 25 mm rod with an M20x1.5 thread.
No, it is not dimensionally interchangeable with ISO 15552 cylinders. You must use AirTAC SC-series mounting accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the profile barrel groove.
