Airtac SAUD Double Rod Cylinder SAUD50X125
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X125 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 125mm stroke, 1/4" 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 SAUD Double Rod Cylinder SAUD50X125
The AirTAC SAUD50X125 is a double-acting, double-rod profile cylinder featuring a 50 mm bore and 125 mm stroke. Because a rod protrudes from both ends, the push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This SKU has no internal magnet, so it cannot accept CMSG or DMSG sensors. It uses a 1/4 inch port and offers a safe working load of roughly 495 N. For vertical lifts, expect a capacity of about 42 kg with a 2:1 safety margin. A Viton H seal option can raise the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X125 Is Used
Twin Tool Stamping
Drives two matched stamping heads simultaneously from one piston, ensuring perfectly synchronized contact on thin sheet metal.
Dual Paddle Diverting
Mounts opposing paddles on each rod end to push packages from either side of a belt without twisting the assembly.
Non-Rotating Clamp
Holds a workpiece securely using the inherent anti-rotation properties of the twin rods during precision machining.
Is the Airtac SAUD Double Rod Cylinder SAUD50X125 the Right Cylinder?
Choose this 50 mm bore when you need 825 N of equal force in both directions. Sizing down, the 40 mm bore yields 528 N both ways. Sizing up, the 63 mm bore provides 1402 N both ways. A double rod is ideal for anti-rotation guidance or driving twin tooling. Mounting is limited to Basic, FA, and LB types compatible with the AirTAC SC series. Since this unit lacks the -S magnet, external sensing is required. At 125 mm stroke, side loads are minimal, but always use external guides for longer strokes.
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 SAUD Double Rod Cylinder SAUD50X125 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers equally.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG, or EMSG switches. You must use external mechanical or optical sensors for position detection.
