Airtac SAU Standard Air Cylinder SAU100X475S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X475S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 475mm stroke, 1/2" 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 SAU100X475S
The AirTAC SAU100X475S is a double-acting profile-type cylinder built around an extruded aluminum barrel. It is engineered to be physically shorter than an ISO 15552 cylinder of the same 100 mm bore, providing a distinct spatial advantage in dense machinery layouts. Sharing mounting accessories with the AirTAC SC series, it delivers substantial thrust: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. The 1/2" port and M20x1.5 rod thread handle the high airflow and mechanical load required for heavy-duty motion.
For practical sizing, plan for a safe working load of about 2356 N (roughly 60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. Alternatively, it can vertically lift about 200 kg with a 2:1 safety margin. The included -S magnet enables position sensing via CMSG, DMSG, or EMSG switches fitted directly into the barrel groove. For high-heat environments up to 150 C, specify the Viton H seal option instead of the standard TPU.

Where the Airtac SAU Standard Air Cylinder SAU100X475S Is Used
Heavy Stamp Press Feed
Pushes thick steel blanks into a stamping die, utilizing the 3927 N push force at 0.5 MPa to overcome material friction and seat the part accurately.
Pallet Dispenser Pusher
Separates empty pallets from a magazine stack; the 475 mm stroke provides the reach needed to index standard pallets into a robotic pickup zone.
Automated Guided Vehicle Lift
Raises a 180 kg payload on an AGV mast, staying safely within the 200 kg vertical lift capacity while the -S magnet confirms upper and lower positions.
Is the Airtac SAU Standard Air Cylinder SAU100X475S the Right Cylinder?
When sizing this 100 mm bore, compare it against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up is unnecessary as this 100 mm bore already tops the range with 3927 N at 0.5 MPa. Because this unit features a 475 mm stroke, you must account for rod bending under side loads—use an external guide rail to prevent premature seal wear and piston scoring. The adjustable 29 mm air cushions at both ends decelerate the heavy payload near stroke end, but they do not function as a brake. If the load must remain suspended when air is lost or the valve is centered, install an external rod lock or a pilot-operated check valve to prevent dangerous piston drift. Utilize SC-series foot (LB) or flange (FA) mounts to secure the body.
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 SAU100X475S FAQ
The 100 mm bore generates a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N, and at 0.9 MPa it pushes 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. Air is supplied via a 1/2" port.
No, it is not dimensionally interchangeable with ISO 15552 brackets; you must use AirTAC SC-series accessories like LB foot or FA flange mounts. However, because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly into the extruded barrel groove for position detection.
