Airtac SAU Standard Air Cylinder SAU100X135S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X135S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 135mm 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 SAU100X135S
The AirTAC SAU100X135S is a double-acting profile-type cylinder engineered to be physically shorter than an ISO 15552 unit of the same bore, yielding a significant space advantage in dense machinery layouts. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, operating via a 1/2" port and a 25 mm carbon steel rod with an M20x1.5 thread. The extruded aluminum barrel features an integrated sensor groove, and because this SKU includes the -S magnet, it is fully primed for CMSG, DMSG, or EMSG electronic or reed switches.
For practical sizing, plan for a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push rating) to account for seal friction and smooth travel. In vertical lifting applications, this translates to hoisting about 200 kg safely with a 2:1 margin. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X135S Is Used
Automotive Pressing
Applies 3927 N of force at 0.5 MPa to seat bearings and stamp light automotive panels in compact assembly cells.
Pallet Diversion
Leverages the 135 mm stroke to push heavy 200 kg pallets onto secondary packaging lines without requiring excessive longitudinal space.
Heavy Load Elevation
Raises loaded material trays vertically, safely lifting around 200 kg thanks to the robust 25 mm rod and high thrust capacity.
Is the Airtac SAU Standard Air Cylinder SAU100X135S the Right Cylinder?
When sizing this 100 mm bore, compare it to neighboring bores: a 63 mm unit provides 1559 N push at 0.5 MPa, while an 80 mm offers 2513 N, making the 100 mm ideal when you need to exceed those limits and tap into 3927 N. You can mount this cylinder using AirTAC SC-series accessories, such as LB foot brackets, FA/FB flanges, or CA/CB clevises, alongside I, Y, F, or U rod knuckles. Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near stroke ends and do not function as a locking brake. To suspend a load safely, integrate 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 SAU100X135S FAQ
This 100 mm bore cylinder features a 1/2" port and generates 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. Its theoretical maximum force is 801 kgf at 1.0 MPa.
It shares mounting accessory compatibility with the AirTAC SC series (like LB, FA, and CA brackets) rather than ISO 15552 standards. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the barrel groove.
