💡 What is a bellows-type flexible coupling used for? These couplings transfer motion between rotating shafts while accommodating misalignment. - Handy for servo and stepper drive setups requiring precise torque transfer. - Absorbs angular misalignment, eccentricity, and end-play for smoother, consistent motion. - Ideal for compact CNC, robotics, and automation tasks where space is tight. - Helps reduce bearing wear by maintaining smooth, stable motion. This makes it a handy choice for reliable, high-performance motion in small, precise machinery.
