💡 What is a bellows-type flexible coupling used for in servo and stepper motor systems? Bellows couplings are designed to handle small shaft misalignment while preserving precise motion. - They compensate angular misalignment in tight spaces
- They provide zero backlash for precise positioning in CNC, 3D printers, and robotics
- They maintain high torsional rigidity for stable motion under load
- They are handy for space constrained installations requiring reliable torque transfer
This setup delivers improved accuracy and performance in compact automation systems.
