Airtac SAU Standard Air Cylinder SAU100X475
The AirTAC Airtac SAU Standard Air Cylinder SAU100X475 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 SAU100X475
The AirTAC SAU100X475 is a double-acting profile-type cylinder engineered for heavy-duty linear motion. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Designed with an extruded aluminum barrel, this unit is notably shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It features a 1/2" port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 2356 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this to 0-150 C. Note that this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic sensors.

Where the Airtac SAU Standard Air Cylinder SAU100X475 Is Used
Heavy Stamp Press Feed
Drives heavy metal blanks into a stamping press, utilizing the 3927 N push force to move 200 kg loads smoothly over the 475 mm travel distance.
Pallet Dispenser Pusher
Indexes empty pallets along a heavy-duty conveyor line, where the compact profile length frees up floor space in tight logistics hubs.
Injection Mold Ejector
Pushes large molded plastic parts out of heavy industrial tooling, relying on the 1/2" port for rapid air exchange and fast retraction.
Is the Airtac SAU Standard Air Cylinder SAU100X475 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores: a 63 mm unit yields 1559 N push at 0.5 MPa, while no larger standard bore exists in the SAU series, making this the maximum thrust option at 801 kgf theoretical max. Because this is a plain cylinder without a magnet, it cannot accept position sensors. To secure a load if air pressure drops or the valve is centered, you must add an external rod lock or a pilot-operated check valve, as the adjustable 29 mm air cushions only decelerate the piston near stroke end and will not hold the load. Mounting relies on AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis. Given the 475 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads.
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 SAU100X475 FAQ
This 100 mm bore cylinder features a 1/2" port and an M20x1.5 rod thread. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, the SAU is a profile-type cylinder that is shorter than an ISO 15552 unit, and you must never claim ISO interchangeability. Mounting compatibility is strictly with the AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis. Additionally, this SKU lacks the -S magnet, so it cannot accept magnetic sensors.
