About this item

The Aluminium Flexible Coupling 5mm x 8mm is a versatile mechanical component designed to connect shafts of different diameters—5mm and 8mm—while accommodating minor misalignments. Commonly used in 3D printers, CNC machines, and DIY projects, this coupling ensures precise motion transfer. Made from durable aluminum, it features a helical design that provides flexibility to compensate for axial, radial, and angular misalignments, reducing mechanical binding and improving system performance. With compact dimensions of approximately 25mm length and 19mm outer diameter, it fits well in space-constrained setups. The coupling includes four M3 set screws, two on each side, to secure a firm attachment to the shafts, minimizing backlash and torsional deflection. This makes it ideal for applications requiring high precision and reliability. Whether assembling a 3D printer, building a CNC machine, or working on custom mechanical projects, the Aluminium Flexible Coupling 5mm x 8mm offers an efficient and dependable solution for connecting shafts with different diameters while ensuring smooth and accurate power transmission.
