💡 What is a bellows-type flexible coupling used for in precision motion systems? A bellows-type flexible coupling provides a compact, no-backlash link that compensates misalignment in servo, CNC, and automation setups. - Absorbs angular misalignment and end-play for smoother drive - Maintains constant velocity and high torsional rigidity for precise positioning - Handy for compact setups where space is tight and reliability matters - Suitable for high torque, low backlash applications in automation This design helps improve accuracy, reduce wear, and boost overall system performance.
