Description
19mm Outer Diameter x 25mm Length, 5mm x 8mm Inner Diameter RB Aluminium Flexible Shaft Coupling
The RB Aluminium Flexible Shaft Coupling is a compact mechanical coupling made to connect 5mm and 8mm shafts in precision motion and transmission systems. With its 19mm outer diameter and 25mm overall length, it is suitable for compact assemblies where reliable shaft joining and smooth rotational movement are required. Its helical slit design helps absorb slight shaft misalignment and reduces stress on connected parts during operation.Constructed from strong aluminium, this one-piece flexible coupling provides zero backlash performance, low rotational inertia, and stable torque transmission. It is a practical choice for CNC systems, 3D printer mechanisms, robotics, and automation equipment where smooth shaft connection and reduced vibration are important.
