In order to establish an optimal combination of materials used for polymer thrust bearings, two types of components (polyetheretherketone (PEEK) races - polytetrafluoroethylene (PTFE) retainer and PEEK races – PEEK retainer) were tested by rolling contact fatigue. Their wear properties were investigated and it was concluded that using a PTFE retainer, the wear loss was improved due to PTFE wear debris attaching to the wear track and acting as a lubricant.

In order to establish an optimal material combination for the production of polymer thrust bearings, two types of components: retainer and PPS races - PPS retainer were tested by rolling contact fatigue (RCF). The wear properties of both bearing types were investigated and a relationship between thrust load, rotation speed and wear loss was established. It is concluded that by using a PTFE retainer, it is possible to improve the

Polyetheretherketone (PEEK) is a tough semi-crystalline thermoplastic polymer with excellent mechanical properties. While abilities of polyphenylenesulfide (PPS) are similar to PEEK, former material cost was lower than later. Polytetrafluoroethylene (PTFE) is well known because of its low friction coefficient and self lubrication ability. The objective of this study is to observe the friction coefficient of hybrid bearings, PTFE retainer sandwiched with PPS-races or PEEK-races. Rolling contact fatigue tests were performed and in situ friction forces wear measured. It is concluded that the PTFE retainer reduced friction coefficient.
