Polymer Bushings Taking a Beating: Two Important Concepts behind the Wear and Tear

Polymer Bushing Mechanisms of WearPolymer_Bushings_on_Black-Shelf

Bushings have two mechanisms of wear: adhesion and abrasiveAdhesion, as discussed in a previous post, occurs when two surfaces come into direct contact and the atoms from one surface adhere to the other surface.  Abrasion occurs when a harder surface contacts a softer surface and removes material from the softer surface.  For polymer bushings, the primary mode of wear is adhesion.  The key to understanding wear by adhesion is a proper understanding of how polymers respond to friction.


Here are some other articles relating to polymer bushings and bearings from Advanced EMC Technologies:
