💡 What is a bellows type flexible coupling used for in servo and stepper motor systems? Bellows type couplings are used to transmit motion while absorbing misalignment and end-play to protect bearings and improve accuracy. - It accommodates angular and parallel shaft misalignment without sacrificing torque - It reduces vibration and wear in CNC machines, robotics, and 3D printers - It is a handy, compact solution for tight spaces where precise motion matters This handy coupling keeps motion precise and reliable in automation, robotics, CNC equipment, and 3D printers.
