Description
19mm Outer Diameter x 25mm Length, 4mm x 6.35mm Inner Diameter RB Aluminium Flexible Shaft Coupling
The RB Aluminium Flexible Shaft Coupling is a compact shaft connector made for joining 4mm and 6.35mm shafts in systems that require smooth and stable rotation. With a 19mm outside diameter and 25mm body length, it is ideal for compact assemblies where precise shaft connection is important. Its spiral beam cut design gives the coupling enough flexibility to accommodate slight shaft misalignment while maintaining efficient torque transfer.Built from strong aluminium, this single-piece flexible coupling is suitable for applications requiring low backlash, reduced vibration, and consistent rotational performance. It can be used in automation equipment, DIY machinery, 3D motion systems, and light mechanical drive setups where dependable shaft coupling is needed.
