A bellows coupling is a type of flexible coupling that uses a metallic bellows as the flexible element to connect two shafts. The bellows allow for the transmission of torque while compensating for angular, axial, and radial misalignments. Known for their torsional rigidity and zero backlash, bellows couplings are ideal for precision applications such as robotics, CNC machines, and measuring instruments. Their lightweight, compact design and ability to operate at high speeds make them a popular choice in industries requiring accurate and reliable performance.
