Factors That Influence Polymer Bushing Performance:  Speed and Pressure - Part 2 in a 3 Part Series

Posted On August 31, 2016


Two values that are very key to the performance of a polymer bushing are the speed and pressure. In this second article of the series, we are going to review how to determine them and what effect they have on bushing performance.

Speed

Running speed is also called bearing speed or surface speed. How you determine depends on how the bushing is going to be used. If it is a rotary bushing, the equation is:

Factors that Influence Polymer Bushing Performance: Mating Hardware - Part 1 in a 3 Part Series

Posted On August 26, 2016


The mating hardware can make or break the life and effectiveness of a polymer bushing.  

The key characteristics of the mating hardware that affect bushing life are the hardness and the surface finish. In this article we are going to discuss the general guidelines for surface roughness, finish, and hardness when using polymer bushings.

Critical Factors: Reverse Engineering Polymer Seals, Bellows, Diaphragms, & Bearings

Posted On May 20, 2016


What is Reverse Engineering?

Reverse engineering means to recreate a part based on available data about it.  Keep in mind that the goal of reverse engineering is not so much as to create a part that looks and feels identical to the original part (although it can be), but rather provides the same (or better) performance as the original part.  The material might be different.  While it will likely fit in the same space envelope, non-critical geometry might not be the same.  However, the part achieves the same purpose and performs the same function.
