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.
Tips: What are the materials typically used in the manufacturing of bellows couplings?
Bellows couplings are typically made of materials that are both strong and flexible, as they are designed to transfer torque between two rotating shafts while compensating for any misalignment. Some of the most commonly used materials for manufacturing bellows couplings include:
- Stainless steel: Stainless steel is a popular choice for bellows couplings due to its high strength, durability, and corrosion resistance. It is also
able to withstand high temperatures, making it suitable for use in a wide range of industrial applications.
- Titanium: Titanium is another popular material for bellows couplings due to its high strength-to-weight ratio and excellent corrosion resistance. It is also biocompatible, making it ideal for use in medical and dental applications.
- Inconel: Inconel is a nickel-based alloy that is known for its high temperature resistance and excellent corrosion resistance in harsh environments. It is often used in aerospace and industrial applications.
- Aluminum: Aluminum is a lightweight material that is often used in bellows couplings for applications that require high-speed rotation. It is also corrosion-resistant, making it suitable for use in humid or corrosive environments.
- Brass: Brass is a copper-based alloy that is often used in bellows couplings for its excellent thermal conductivity and corrosion resistance. It is also easily machinable, making it a cost-effective option for many applications.
