Airtac SAU Standard Air Cylinder SAU100X950S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X950S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 950mm 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 SAU100X950S
The AirTAC SAU100X950S is a double-acting profile-type cylinder engineered for heavy-duty linear motion. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Featuring an extruded aluminum barrel, this unit is physically shorter and more compact than a standard ISO 15552 cylinder of the same 100mm bore, granting you a distinct space advantage in tight machine layouts. It operates on a 1/2" air port and includes a 25mm carbon steel rod with an M20x1.5 thread.
Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG electronic switches directly into the profile barrel groove for precise end-of-stroke detection. For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. Alternatively, you can reliably lift a 200 kg part vertically using a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU100X950S Is Used
Press Ejection Systems
Handles heavy stamping ejection tasks where the 3927 N push force at 0.5 MPa easily clears large metal blanks from a press bed over the extended 950mm distance.
Pallet Dispenser Mechanism
Ideal for pushing empty or loaded pallets into a strapping station, utilizing the 200 kg vertical lift equivalent to manage heavy wood or plastic pallets safely.
Heavy Log Transfer
Deploys the full 950mm stroke to push bulky automotive components or industrial logs across a conveyor gap, relying on the integrated magnet for position feedback.
Is the Airtac SAU Standard Air Cylinder SAU100X950S the Right Cylinder?
When sizing this 100mm bore, compare it against its neighbors: a 63mm bore yields 1559 N of push force at 0.5 MPa, whereas an 80mm bore provides 2513 N. If you need even more power, note that the 100mm bore is the largest in the SAU family, maxing out at an 801 kgf theoretical limit at 1.0 MPa. Mounting is straightforward using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises.
Because this model features a 950mm stroke, you must account for side-load risks and rod-bending moments; always use an external guide rail to support the load and prevent premature seal wear. Additionally, a plain cylinder drifts when air is lost or the valve is centered, as the adjustable 29mm air cushion only decelerates the piston near the end of travel and acts purely as an end-of-stroke dampener, never a brake. To suspend a load safely mid-stroke, 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 SAU100X950S FAQ
This 100mm bore cylinder provides 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 it reaches a theoretical maximum of 801 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s, uses a 1/2" port, and features a 29mm adjustable air cushion at both ends.
You cannot use ISO 15552 brackets, as the SAU is a distinct compact profile cylinder that is shorter than an ISO equivalent. You must use AirTAC SC-series mounting accessories like LB foot or FA flange brackets. However, because this model has the -S magnet, it fully supports CMSG, DMSG, and EMSG sensors in the barrel groove.
