Airtac SAU Standard Air Cylinder SAU100X370
The AirTAC Airtac SAU Standard Air Cylinder SAU100X370 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 370mm 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 SAU100X370
The AirTAC SAU100X370 is a double-acting profile-type cylinder featuring a 100mm bore and a 370mm stroke. It utilizes a hard-anodized extruded aluminum barrel with an integrated sensor groove, making it significantly shorter and more compact than a standard ISO 15552 cylinder of the same bore. Delivering 3927 N of push force at 0.5 MPa, it is built for heavy-duty automation. The unit features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at both ends to absorb impact.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. In vertical lift applications, this translates to lifting about 200 kg with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches. If your machine environment exceeds 70 C, you can specify the Viton (H) high-temperature seal option to safely operate up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X370 Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive parts stamping line, utilizing the 3927 N push force to form steel brackets reliably.
Pallet Dispenser
Pushes empty pallets into a packaging conveyor lane, where the 370 mm stroke provides the exact reach needed to load the next unit.
Vertical Lift Gate
Raises a 180 kg material lift gate in a distribution center, staying safely within the 200 kg vertical lift capacity to ensure smooth cargo transfer.
Is the Airtac SAU Standard Air Cylinder SAU100X370 the Right Cylinder?
When sizing this actuator, compare it against adjacent bores to ensure optimal performance. Stepping down to the 80mm bore reduces the push force to 2513 N at 0.5 MPa, while the 100mm bore provides 3927 N, and there is no larger standard SAU option. Mounting is highly flexible because it shares identical LB foot, FA/FB flange, and CA/CB clevis accessories with the AirTAC SC series. You can also utilize I, Y, floating (F), or universal (U) rod knuckles for specific linkage requirements.
Because this model features a 370 mm stroke, you must account for side-load risks and potential rod-bending forces; always use external guide rails to support the load and prevent premature seal wear. Additionally, a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. The adjustable cushions only decelerate the piston near the stroke end and act purely as an end-of-stroke brake, never a holding device. For suspended or gravity-loaded applications, install 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 SAU100X370 FAQ
The SAU100X370 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. It features a 100mm bore, 370mm stroke, 1/2" port, M20x1.5 rod thread, 29 mm cushions, and operates at speeds of 30-800 mm/s.
No, this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches. Regarding mounting, it is a compact profile cylinder that is shorter than an ISO 15552 unit, but it shares mounting accessories exclusively with the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis brackets.
