Description
19mm Outer Diameter x 25mm Length, 4mm x 10mm Inner Diameter RB Aluminium Flexible Shaft Coupling
The RB Aluminium Flexible Shaft Coupling is a compact shaft joining component designed to connect 4mm and 10mm shafts in precision mechanical and motion transfer systems. With a 19mm outer diameter and 25mm total length, it is suitable for compact assemblies where stable rotation and secure shaft connection are required. Its spiral slit body design helps accommodate slight shaft misalignment while minimizing binding during operation.Constructed from durable aluminium, this one-piece flexible coupling delivers zero backlash performance, low inertia, and reliable torque transmission. It is a practical choice for CNC applications, 3D printing systems, robotic mechanisms, and motor coupling setups where reduced vibration and smooth motion are important.
