Airtac SAU Standard Air Cylinder SAU100X210
The AirTAC Airtac SAU Standard Air Cylinder SAU100X210 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 210mm 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 SAU100X210
The AirTAC SAU100X210 is a double-acting profile-type cylinder built around an extruded aluminium barrel. It is purposefully shorter than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, operating on a 1/2 inch port with a 25 mm rod.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa. Vertically, this translates to lifting about 200 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensor switches. 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 SAU100X210 Is Used
Heavy Pallet Lifting
Drives the primary elevation stage in automated palletisers, smoothly lifting 200 kg loads using its 3927 N push force at 0.5 MPa.
Injection Mould Extraction
Extracts heavy automotive moulded parts from presses, utilising the 210 mm stroke and compact profile to fit within tight clamping areas.
Press Ejection
Ejects dense metal stampings from hydraulic presses, where the 1/2 inch port ensures rapid exhaust and fast 30-800 mm/s cycling.
Is the Airtac SAU Standard Air Cylinder SAU100X210 the Right Cylinder?
When sizing this 100 mm bore, compare its 3927 N push force at 0.5 MPa against the neighbouring 80 mm bore, which provides 2513 N. If you need more power, there is no larger standard SAU bore, so moving to a custom multi-cylinder setup is required. Because this is a non-magnetised SKU, position sensing is unavailable; if your cycle requires end-of-stroke confirmation, select an SAU100X210-S variant instead. Mounting uses AirTAC SC-series accessories like LB foot or FA flange.
With a 210 mm stroke, side-load risks are moderate, but always ensure rigid guidance for heavy 200 kg loads to prevent rod bending. Note that a standard cylinder drifts when air is lost; the adjustable 29 mm air cushion only decelerates the piston near the end caps and does not act as a brake. To hold a load securely during an air failure, 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 SAU100X210 FAQ
The SAU100X210 uses a 1/2 inch port. 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.
It is not dimensionally interchangeable with ISO 15552; mounting accessories must match the AirTAC SC series, such as CA or CB clevis brackets. Additionally, this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors.
