Airtac SAU Standard Air Cylinder SAU100X220
The AirTAC Airtac SAU Standard Air Cylinder SAU100X220 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 220mm 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 SAU100X220
The AirTAC SAU100X220 is a double-acting profile-type standard cylinder featuring a 100 mm bore and 220 mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty industrial tasks. Its extruded aluminum barrel with an integrated sensor groove is designed to be significantly shorter than an ISO 15552 cylinder of the same bore, providing a distinct space-saving advantage in tight machinery layouts.
Equipped with a 1/2" air port and an M20x1.5 rod thread, this unit operates at speeds of 30-800 mm/s with adjustable air cushions at both ends. For practical sizing, plan for a safe working load of about 2356 N (roughly 60% of the 0.5 MPa rating) to account for seal friction. Vertically, it can lift approximately 200 kg with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X220 Is Used
Heavy Stamping Press
Drives a 150 kg upper die in a compact metal stamping press, utilizing the 3927 N push force to form steel components reliably.
Pallet Dispenser
Pushes empty wooden pallets into an automated packaging line, where the shorter profile barrel conserves floor space in dense conveyor zones.
Vertical Lift Gate
Actuates a 180 kg material lift gate, safely operating within the 200 kg vertical lift capacity calculated with a 2:1 safety margin.
Is the Airtac SAU Standard Air Cylinder SAU100X220 the Right Cylinder?
When sizing this 100 mm bore model, compare it to adjacent bores: the 80 mm version offers 2513 N push at 0.5 MPa, while there is no larger standard SAU bore. If your application requires position sensing, you must select an SAU100X220-S variant instead, as this non-magnetized SKU cannot accept a sensor switch. Mounting is highly flexible thanks to compatibility with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near the end of stroke and does not function as a locking brake. For suspended or vertical loads that must remain stationary during air loss, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU100X220 FAQ
This 100 mm bore cylinder features a 1/2" air port and an M20x1.5 rod thread. At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, so you can use SC LB, FA, FB, CA, and CB brackets. Additionally, this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
