The cylindrical aluminum body, with an outer diameter of approximately 19 mm, features ring-shaped cuts in the center that create a flexible section.\u003c\/p\u003e \u003cp\u003eThis flexible center section compensates for angular, axial, or parallel misalignment between the two shafts without breaking. Each end has a bore for the shaft and two hex socket grub screws that clamp the inserted shaft securely. This ensures that both shafts rotate synchronously.\u003c\/p\u003e \u003cp\u003eThe bores may have different diameters depending on the version, allowing connections between shafts of different sizes. This means the coupling can be used flexibly with different combinations of motor and driven shaft. As a purely mechanical component, it does not transmit electrical signals.\u003c\/p\u003e \u003cp\u003eTwo shaft ends with matching diameters are required, depending on the selected version. No splined or flat-key preparation on the shaft ends is necessary; the coupling operates solely through the clamping force of the grub screws.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eDuring installation, the grub screws should be tightened to an appropriate torque to ensure a secure fit without causing damage. This component is intended exclusively for building prototypes and for testing and development purposes. For applications involving high torque or vibrations, consult a qualified electrician for a safety assessment before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x shaft coupling - 4 * X mm\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045694312797,"sku":"3D-A-1-XX","price":1.3,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/funduino.com\/en\/products\/shaft-coupling-4-x-mm","provider":"Funduino","version":"1.0","type":"link"}
