Description
19mm Outer Diameter x 25mm Length, 4mm x 4mm Inner Diameter RB Aluminium Flexible Shaft Coupling
The RB Aluminium Flexible Shaft Coupling is a precision-machined shaft connector designed to join 4mm and 4mm shafts in motion control and power transmission systems. With a compact 19mm outer diameter and 25mm overall length, it is well suited for CNC equipment, 3D printers, robotics, motor assemblies, and other applications where smooth shaft coupling is required. Its helical spiral cut structure allows flexibility to accommodate slight shaft misalignment and helps reduce mechanical stress during operation.Manufactured from durable aluminium, this one-piece flexible coupling provides zero backlash torsional performance, low rotational inertia, and dependable long-term use.
