As friction-reducing components, it is essential that bushings are constructed from wear-resistant materials that provide good sliding properties. While bushings can be fabricated from a variety of plastics and metals, bronze provides several distinct advantages over alternative options in heavy-load applications. As an inherently moldable and easy-to-machine material, bronze is well-suited for achieving a range of bushing designs.
The bronze alloy used in cast bronze bushings undergoes a continuous or centrifugal casting process, giving the metal a finer grain structure and improved mechanical properties. The bronze alloy cast bar is then cut and processed into the finished bushing using a computer numerical control (CNC) lathe or other precision machining method. Casting bronze bushings exhibit excellent structural strength, durability, and resistance to compressive forces, making them well-suited for harsh, high-wear applications. They can also withstand high temperatures without losing their strength.
