💡 What is a bellows-type flexible coupling used for in precision motion systems such as servo and stepper motor setups?

This explanation covers the role of bellows couplings in absorbing misalignment while transmitting torque.

• Absorbs angular, axial, and parallel misalignment while keeping shafts aligned
• Maintains consistent torque with minimal backlash for accurate positioning
• Ideal for CNC, robotics, and automation where smooth motion matters

This handy design improves stability and performance in precision motion projects.

This design reduces vibration, improves accuracy, and keeps motor drives smooth in real-world robotics and CNC tasks.
