Airtac SAU Standard Air Cylinder SAU100X15S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X15S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 15mm 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 SAU100X15S
The AirTAC SAU100X15S is a double-acting profile-type cylinder engineered for high-force tasks in tight machine envelopes. It is purposefully shorter than an ISO 15552 cylinder of the same 100 mm bore, yielding a distinct space advantage without sacrificing power. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, utilizing a 1/2 inch air port and a 25 mm rod with an M20x1.5 thread.
Because this 15 mm stroke is a non-standard made-to-order size, it provides exact short-travel clamping. Plan for a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. Alternatively, it can vertically lift about 200 kg with a 2:1 safety margin. The included -S magnet enables CMSG, DMSG, or EMSG sensors in the profile groove, and a Viton H high-temperature seal option extends operation to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X15S Is Used
Heavy Press Clamping
Uses the 3927 N push force at 0.5 MPa to secure thick steel plates in an automated stamping press via a short 15 mm travel stroke.
Injection Molding Ejector
Provides a compact, high-impact ejection burst for dense plastic parts, leveraging the space-saving profile barrel to fit tight mold bases.
Pallet Brake Actuator
Drives a heavy-duty mechanical stopper on a conveyor line, safely arresting pallets using the 200 kg vertical lift equivalent capacity.
Is the Airtac SAU Standard Air Cylinder SAU100X15S the Right Cylinder?
When sizing this unit, compare it against adjacent bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. This 100 mm bore pushes 3927 N at 0.5 MPa, making it the top choice when those smaller options lack thrust. Mounting relies on AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Note that a plain SAU cylinder drifts if air is lost or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near stroke end. For secure load holding, add 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 SAU100X15S FAQ
This 100 mm bore cylinder features a 1/2 inch air port and delivers 3927 N push / 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
It is not dimensionally interchangeable with ISO 15552; use AirTAC SC-series accessories (LB, FA, FB, CA, CB) for mounting. The -S magnet allows CMSG, DMSG, and EMSG switches to sit directly in the profile barrel groove.
