Description
19mm Outer Diameter x 25mm Length, 5mm x 6.35mm Inner Diameter RB Aluminium Flexible Shaft Coupling
The RB Aluminium Flexible Shaft Coupling is a compact mechanical connector designed to couple 5mm and 6.35mm shafts in precision motion and transmission systems. With a 19mm outer diameter and 25mm body length, it is suitable for compact assemblies where secure shaft connection and stable rotation are important. Its helical beam cut structure helps compensate for slight shaft misalignment while reducing stress on connected components during operation.Made from durable aluminium, this one-piece flexible coupling offers zero backlash performance, low rotational inertia, and reliable torque transfer. It is well suited for CNC equipment, 3D printer systems, robotics, and automation mechanisms where smooth operation and reduced vibration are required.
