💡 What is a bellows-type flexible coupling used for? A bellows-type flexible coupling helps absorb misalignment and end-play while keeping torque transfer smooth and accurate. - Absorbs angular and axial misalignment with minimal vibration - Maintains constant velocity transmission for precise positioning in CNC and robotics - Compact, high rigidity design delivers reliable performance with low backlash - Ideal for servo motors and precision drives where tight speed and torque control matter This handy coupling keeps machines running smoothly with predictable performance and long service life.
