Bronze Eccentric Bushing

A bronze eccentric bushing, also known as a bronze eccentric bearing or bushing, is a mechanical component used in various applications to provide rotational support and reduce friction between two moving parts. It is typically made from bronze, a material known for its good wear resistance and self-lubricating properties.

Casting Bronze Eccentric Bushings

The term “eccentric” refers to the fact that the inner diameter of the bushing is not concentric with the outer diameter. This design allows for adjustable positioning of the bushing, which can be beneficial in certain applications where precise alignment or adjustment is required.

Bronze eccentric bushings are typically manufactured using a process called centrifugal casting, which helps ensure a uniform and dense material structure. This is important for maintaining the desired mechanical properties and wear resistance of the bushing.

The eccentric design involves the off-center positioning of the inner bore in relation to the outer diameter. This allows for the adjustment of the relative position between two connected components when the bushing is rotated. Eccentricity can be controlled to provide varying degrees of adjustment, allowing for fine-tuning in specific applications.
