Airtac SAUD Double Rod Cylinder SAUD50X65
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X65 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 65mm 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 SAUD50X65
The AirTAC SAUD50X65 is a double-acting, double-rod profile cylinder. A 20 mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields exactly 825 N of output force in both directions at 0.5 MPa. The unit is notably shorter than an ISO 15552 cylinder of the same bore.
Because the second rod provides inherent anti-rotation guidance, this 50 mm bore model excels in synchronized twin-tool tasks. The 1/4" port drives the piston at 30-800 mm/s. As a practical computed buyer insight, the safe working load is roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG switches.

Where the Airtac SAUD Double Rod Cylinder SAUD50X65 Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one actuator, using the dual rods to maintain parallel alignment without twist.
Dual Transfer Pushers
Pushes alternating lanes of parts on a conveyor belt, leveraging the equal bidirectional force for consistent cycling.
Vertical Lift Stops
Raises and lowers a 42 kg pallet stop gate, relying on the rigid double-rod structure to prevent binding under side loads.
Is the Airtac SAUD Double Rod Cylinder SAUD50X65 the Right Cylinder?
Select this 50 mm bore if your mechanism requires strict non-rotating accuracy or needs to drive two tools at once from a single actuator. It delivers an equal 825 N both ways at 0.5 MPa. If you need less force, the adjacent 40 mm bore provides 528 N; if you need more, step up to the 63 mm bore for 1402 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this is a non-magnetized SKU, you cannot mount sensors. For any application, remember the air cushions only decelerate near the stroke ends; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for load holding.
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 SAUD50X65 FAQ
The force is equal in both directions because a rod exits both ends. It produces 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
No, this specific SKU is not built with a piston magnet. You must select a -S variant to use CMSG, DMSG, or EMSG switches for position sensing.
