Four TPI Core Technologies in Bicycle Application

TPI bearings are well-known and widely used in bicycle industry. For example, the hubs and wheelsets of Rio 2016 Olympic championship bicycle was supplied by a Swiss high-end bicycle component manufacturer who has long term cooperation with TPI. TPI has four core technologies in bicycle industry and they are as follows:

Bearing failure causes statistics

Based on years of bearing design and manufacturing experience, TPI is able to analyze the causes of bearing damage and failure. In previous technical paragraphs, effective solutions for different types of bearing failure were provided. According to the bearing investigation done by TPI, the top bearing failure causes would be, 1. Indentations from particles, 2. Deformation by misassembling, 3. Poor precision of shaft and housing. The percentage of each causes as shown below.

Deformation by Misassembling Causes and Countermeasures

How: Incorrect mounting method and mounting tool defect may lead to an overload force between bearing rings and rolling elements. This will cause a certain indentation on bearing raceway and rolling elements surface.
