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

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.

Why Nylon Bushings are a Good Choice for the Bicycle Industry

Reinforced Nylon Bushing Option

Plain bearings in bicycle applications get subjected to a good amount of abuse, from high shock loads as the rider makes their way over uneven terrain, to potentially high speeds as some bikes can reach speeds in excess of 70 mph.  Then there are the issues of environmental contaminants, namely water, mud, sand, and other debris.  That means that cleaning is required, often in the form of steam.  It takes a special type of bushing to stand up under these types of rigors.  One of the options to consider is reinforced nylon.
