Description

19mm Outer Diameter x 25mm Length, 3mm x 6mm Inner Diameter RB Aluminium Flexible Shaft Coupling

The RB Aluminium Flexible Shaft Coupling is a compact and reliable component designed to connect 3mm and 6mm shafts for smooth and efficient power transmission. With a 19mm outer diameter and 25mm length, this coupling is suitable for use in CNC machines, 3D printers, stepper motor assemblies, robotics, and other precision motion control systems. Its spiral cut design provides flexibility that helps compensate for minor shaft misalignment while reducing binding during operation.

Made from durable aluminium, this one-piece flexible coupling offers zero backlash torsional stiffness, low moment of inertia, and long-lasting performance in demanding applications. It helps protect connected shaft members from the harmful effects of misalignment, vibration, shock loads, and shaft expansion, making it an excellent choice for precision drive systems and motion control assemblies.
