High speed bushings can be found in applications as diverse as agricultural equipment and rollercoasters. When it comes to high speed applications, however, polymer bushings are often underestimated.
In this blog post, we are going to discuss the top four polymer materials for high speed bushings.

There is far more to selecting a polymer bushing than just making sure the PV limit is acceptable and the dimensions are adequate.
Polymer bushings can be produced by a variety of methods, such as injection molding, casting, machining, or compression molding. In this post, we are going to compare the pros and cons of injection molded versus machined polymer bushings.
One of the most important design decisions when selecting a bushing is choosing the right material to provide optimum performance. In this blog post, we will look at the five most popular polymer bushing materials – PTFE, PEEK, Nylon, Ryton®, and UHMW PE – and what they have to offer.
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.
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:

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.
PTFE, better known by its DuPont tradename of Teflon, is a popular choice for polymer bearings and bushings – especially for applications involving high speeds and high temperatures. In this blog post, we will look at seven reasons why this is so.
PEEK, which stands for polyetheretherketone, is a well-known engineering thermoplastic. It has become a popular choice for bushings that must operate in demanding high speed, high temperature environments.
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.
