Engineer’s Choice for Low-cost High-volume Polymer Bushings?

High-Volume Low-Cost Plastic Bushings

In this article, we are going to discuss what the best choices are for high-volume low-cost plastic plastic-bushings-cost-effective-Advanced-EMC.pngbushings.  When an engineer is designing a part to be manufactured, there are two approaches: 

  1. the first is to choose an appropriate material, then select a manufacturing process compatible with the material;
  2. the second is to select a manufacturing process, then choose an appropriate material from the ones that are compatible with that process. 

Let’s try answering the question for today’s article by starting with manufacturing processes for plastics.

Review of PV for Plain Polymer Bearings

In this article, we are going to review some of the basic principles behind the PV value, and take a look at some PV values for commonly used bearing materials.

Introduction

The amount of wear a bearing is going to experience is related to the bearing pressure and the running velocity.  The more pressure applied to the bearing, the faster it will wear; similarly, the faster the bearing surface speed, the more wear will occur.  Did you ever wonder why?  One clue lies in the amount of heat that is generated as a result of interaction between the bearing and the shaft.  The more heat that is generated, the faster the bearing will wear.  One value that represents this relationship between heat generated and the resulting wear is the PV value.  You will see this value used as a key part of the material selection process when specifying a bearing.
