Applications

Bellows couplings are commonly used in robotics, medical equipment, semiconductor manufacturing, and aerospace industries. Bellows couplings can transmit torque and rotational motion while compensating for misalignments, which makes them ideal for applications where high accuracy and repeatability are critical.

Bellows couplings applications

Tips: What is a bellows coupling?

A bellows coupling is a type of flexible coupling used to transmit torque and motion between two rotating shafts that are slightly misaligned or not precisely aligned. It consists of a series of thin metal bellows arranged in a circular shape, with two flanges or hubs attached to each end.

The bellows are made of thin metal sheets, usually stainless steel, that are welded together in a convoluted shape. This allows them to expand and contract, while maintaining their shape and stiffness, which makes them ideal for coupling applications.

When installed between two shafts, the bellows coupling allows for a small amount of misalignment or axial motion between them, while still transmitting torque with high accuracy and minimal backlash. It can also help to dampen vibration and shock loads, which can help to reduce wear and tear on the system.

Bellows couplings are commonly used in applications where precise motion control is required, such as robotics, CNC machines, and semiconductor manufacturing equipment. They are also used in aerospace, medical, and other industries where high reliability and precision are critical.

Existing reviews of 4-8mm Stainless Steel Bellows Coupling
It can meet my needs
I purchased this 4-8mm stainless steel corrugated coupling for my DIY project, which involves connecting a small stepper motor to the lead screw of a 3D printer. In my project, there was a slight deviation in the connection between the motor and the lead screw, but this coupling effectively absorbed this misalignment without causing excessive vibration or oscillation.
