The Anatomy of a Bushing


Bushings are fully customizable based on the application and performance needs. They are available in a variety of compositions with different features. Below is a simple breakdown of bearing options:

Bearing Features

  • Chamfer: Chamfers are angles found on the edge face of a bushing. The 20-45 degree angle guides the bushing into the housing bore.
  • Flange: A flange is the perpendicular flat formed surface on the end of a bushing. Flanges act as a stopping point during the press fit and manage axial thrust force in the application.
  • Split: The split is the result of two blank edges meeting to form the bushing cylinder shape. The split is either straight or a clinch butt joint.


Lubrication Options

  • Self-Lubricating: Bushings that do not require maintenance are known as self-lubricating. They can have a number of materials applied to the steel backing to allow for this feature. Some examples include various formulations of PTFE, POM, bronze, etc.
  • Pre-Lubricating: If a bushing requires oil or grease to be present during service, the bushing can have grooves or pockets into the bearing surface. The pockets can be filled with a solid lubricant or work as a reservoir to provide lubrication at startup until grease or oil is introduced.
