Airtac SAU Standard Air Cylinder SAU100X375
The AirTAC Airtac SAU Standard Air Cylinder SAU100X375 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 375mm 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 SAU100X375
The AirTAC SAU100X375 is a double-acting profile-type cylinder engineered to be physically shorter than an ISO 15552 unit of the same bore, providing a distinct spatial advantage in cramped heavy machinery. It delivers a robust 3927 N of push force at 0.5 MPa, making it ideal for substantial industrial loads. The extruded aluminum barrel features an integrated sensor groove, though this specific SKU lacks the -S magnet and therefore cannot support CMSG, DMSG, or EMSG electronic switches. The unit operates on a 1/2" port with a 25 mm hard-chrome plated rod, utilizing adjustable air cushions at both ends to decelerate the piston smoothly over its 375 mm travel.
For practical sizing, plan for a safe working load of roughly 2356 N—about 60 percent of the 0.5 MPa push rating—to account for seal friction and smooth travel dynamics. In a vertical lifting scenario, this translates to hoisting approximately 200 kg with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, but selecting the Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU100X375 Is Used
Heavy Stamp Press Ejection
Ejects thick metal blanks from a 400-ton stamping press, utilizing the 3927 N push force to overcome die friction reliably within a confined cell footprint.
Pallet Dispenser Mechanism
Pushes empty wooden pallets into a high-speed packaging line, where the 375 mm stroke provides the necessary travel to index a single pallet from a vertical magazine.
Automated Log Sorter Gate
Actuates a heavy diverter gate on a lumber conveyor, depending on the 801 kgf theoretical maximum force to withstand impact loads from moving timber.
Is the Airtac SAU Standard Air Cylinder SAU100X375 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force margins carefully. If your application requires less thrust, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, whereas this 100 mm unit provides 3927 N. Since this is the largest standard SAU bore, moving up in force requires a different cylinder family. Because this model lacks the -S suffix, it cannot accept magnetic position sensors; if your control system requires end-of-stroke detection, you must select an SAU100X375-S variant instead. Mounting hardware—including LB foot brackets, FA/FB flanges, and CA/CB clevises—shares full compatibility with the AirTAC SC series.
With a 375 mm stroke, the 25 mm rod is subjected to higher bending moments under off-center loads. To prevent premature seal wear and rod damage, implement an external guide rail or linear bearing to absorb side loads, ensuring the cylinder remains strictly a linear thrust provider. Furthermore, a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve to secure the load mechanically.
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 SAU100X375 FAQ
This 100 mm bore cylinder features a 1/2" port and generates 3927 N push and 3681 N pull at 0.5 MPa. 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 and uses AirTAC SC-series mounting accessories exclusively, such as LB foot, FA/FB flange, and CA/CB clevis brackets. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to an -S model.
