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.

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.
There are a variety of places where you can find composite bushings in a bicycle, including the headset, pedals, brake lever, front and back derailleurs, and the rear suspension, just to name a few. In this article, we are going to look at the bushings used in rear hubs.
Many people wrongly assume that a polymer rear hub bushing, instead of a metal one, is a cheap substitution made by hub manufacturers. Nothing could be further from the truth! Let’s talk about how to select a proper material for a rear hub polymer bushing that will far outshine its metallic counterparts.

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 bushings. When an engineer is designing a part to be manufactured, there are two approaches:
- the first is to choose an appropriate material, then select a manufacturing process compatible with the material;
- the second is to select a manufacturing process, then choose an appropriate material from the ones that are compatible with that process.

Nylon Bushing Differences:
Ever wonder what the difference is between Nylon 6 and Nylon 66? What about Nylon MDS? In this article, we are going to explore the difference between the types of nylon commonly used in bushings, and how that affects their potential applications.

Food & Dairy Bearings and Bushings:
Bearings and bushings can be found in almost every step in food or dairy processing industries. Polymers are a popular choice for bearings and bushings in the food and dairy industry, both at the design stage and when retrofitting. Because they are greaseless, the can provide a more sanitary environment for food processing. They don’t require the maintenance that metal bearings and bushings require, thus reducing downtime for maintenance. Their durability results in longer mean times to failure. They are usually much more resistant to corrosion and much less chemically reactive than metal bearings and bushings. They also weight much less than equivalent metal bearings and bushings.

Plastic Molded Bearings vs. Powdered Metal Bushings
Engineers are turning to molded plastic bushing and bearings as a replacement for powdered and sintered metal wear components. In this article, we are going to take a look at four specific reasons why.
Other articles on advanced polymer bearings and bushing:
Polymer bushings can be made from a variety of plastics, including Nylon, PEEK, Acetal, PPS, and Teflon. In this article, we are going to look at some fast facts about one particular type of polymer bushing: Nylon bushings. Nylon bushings are injection molded or cast, hence the term “molded bushings.” They are usually available as sleeved bushings of flanged bushings.
