Airtac SAUD Double Rod Cylinder SAUD50X165S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X165S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 165mm 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 SAUD50X165S
The AirTAC SAUD50X165S is a double-acting double-rod profile cylinder featuring a 50mm bore and 165mm stroke. Because a rod exits both ends, the push and pull force is equal at 825 N each way at 0.5 MPa. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. This unit includes the -S magnet option for position sensing.
With a 1/4" port and M16x1.5 rod thread, it delivers a computed safe working load of roughly 495 N (about 60% of the 0.5 MPa figure). This translates to a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. You can also specify Viton H seals to raise the operating temperature limit to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X165S Is Used
Synchronized Transfer
Drives two parallel pick-and-place grippers simultaneously from one piston, keeping motion perfectly synchronized without extra linkage.
Cam-Actuated Sensing
Uses the protruding back rod to trip a CMSG or DMSG switch directly, providing precise end-of-stroke confirmation in tight spaces.
Anti-Rotation Tooling
Prevents twist during vertical pressing or pin insertion by using the dual rods as integral guides for the end effector.
Is the Airtac SAUD Double Rod Cylinder SAUD50X165S the Right Cylinder?
When sizing this double-rod unit, consider the adjacent bores: the 40mm version yields 528 N both ways, while the 63mm provides 1402 N. Choose the SAUD50X165S when your application demands anti-rotation guidance, twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. The -S magnet allows CMSG, DMSG, or EMSG switches. For this 165mm stroke, ensure external guide rails support any lateral loads to prevent binding.
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 SAUD50X165S FAQ
The force is equal in both directions due to the 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" port supplies air to both chambers equally.
No, a plain double-rod cylinder will drift without live air, as the adjustable cushions only decelerate near stroke end. For vertical load holding, install an external rod lock or pilot-operated check valve.
