Airtac SAUD Double Rod Cylinder SAUD50X550
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X550 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 550mm 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 SAUD50X550
The AirTAC SAUD50X550 is a double-acting, double-rod profile cylinder featuring a 50mm bore and 550mm stroke. Because a rod protrudes from both ends, the push and pull output is identical, delivering 825 N of force each way at 0.5 MPa. The extruded aluminum barrel keeps the overall body shorter than a standard ISO 15552 unit of the same size. This model uses a 1/4 inch port and M16x1.5 rod threads.
Without the -S suffix, this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors. For design planning, the computed safe working load is roughly 495 N (about 60% of the 825 N figure), translating to a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. A plain cylinder drifts without live air; the adjustable 21mm cushions only decelerate near stroke end, so add an external rod lock for held loads.

Where the Airtac SAUD Double Rod Cylinder SAUD50X550 Is Used
Twin-Tool Transfer
Drives two opposing grippers to pick and place parts from both sides of a conveyor simultaneously without twisting.
Balanced Lift Station
Raises and lowers a 42 kg machining fixture with equal force in both directions, ensuring smooth vertical travel.
Non-Rotating Clamp
Holds a workpiece securely from both ends during milling, using the dual rods to resist torsional deflection.
Is the Airtac SAUD Double Rod Cylinder SAUD50X550 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 this 50mm model when your application demands equal push and pull forces, anti-rotation stability, or the ability to drive twin tooling simultaneously. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. At 550mm, this stroke is well within the 1200mm standard limit, but you must use external guides to prevent rod bending under side loads. Note that because this SKU lacks the -S magnet, it cannot support position sensing.
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 SAUD50X550 FAQ
The force is equal in both directions due to the double-rod design: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the 1/4 inch port feeds the 50mm bore.
No, this specific SKU does not include a magnet. You must select a model with the -S suffix to mount CMSG, DMSG, or EMSG switches. The rear rod on a double-rod unit can also trip external mechanical switches.
