Airtac SAU Standard Air Cylinder SAU100X450
The AirTAC Airtac SAU Standard Air Cylinder SAU100X450 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 450mm 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 SAU100X450
The AirTAC SAU100X450 is a double-acting profile-type cylinder featuring an extruded aluminum barrel that is noticeably shorter than an ISO 15552 unit of the same bore. It delivers robust thrust, pushing with 3927 N and pulling with 3681 N at 0.5 MPa. The 1/2" port and M20x1.5 rod thread equip it for heavy-duty cycles, while the 29 mm adjustable air cushions at both ends decelerate the piston smoothly.
For practical sizing, plan for a safe working load of roughly 2356 N at 0.5 MPa, accounting for seal friction to ensure smooth travel. Alternatively, it lifts about 200 kg vertically with a 2:1 safety margin. Since this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors. 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 SAU100X450 Is Used
Heavy Press Operation
Drives a 200 kg stamping die in an automotive line, utilizing the 450 mm travel to clear the tooling during part extraction.
Pallet Discharge Gate
Actuates a heavy diverter gate on a packaging conveyor, using the 3927 N push force to redirect loaded pallets smoothly.
Injection Mold Ejector
Pushes large molded plastic components out of a press, relying on the adjustable 29 mm cushions to halt the 450 mm stroke without shock.
Is the Airtac SAU Standard Air Cylinder SAU100X450 the Right Cylinder?
When sizing this 100 mm bore actuator against its neighbors, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, while no larger standard SAU bore exists. If your application demands holding a load vertically or mid-stroke, remember this base cylinder will drift if air pressure drops or the valve centers; the integrated air cushion only decelerates the piston near the end caps and acts as no brake. You must add an external rod lock or a pilot-operated check valve for secure positioning. Mounting hardware matches the AirTAC SC series, utilizing LB foot, FA/FB flange, or CA/CB clevis brackets.
Because the 450 mm stroke is substantial, carefully manage side loads to prevent rod bending. Incorporating an external guide rail ensures the piston rod absorbs minimal lateral stress, preserving seal integrity over a long service life.
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 SAU100X450 FAQ
At 0.5 MPa it pushes with 3927 N and pulls with 3681 N. At 0.7 MPa the push force is 5497 N, reaching 7068 N at 0.9 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. It features a 1/2" port, a 25 mm rod, an M20x1.5 rod thread, and operates at speeds of 30-800 mm/s.
It is not an ISO 15552 cylinder, though it is more compact and shares mounting dimensions strictly with the AirTAC SC series (LB, FA, FB, CA, CB). Additionally, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
