Overview

Rolling contact fatigue tests show jet cooling improved PEEK-PTFE bearing life by 900% under dry conditions, indicating thermal management is crucial.

Key Points

  • Using a jet cooler enhanced bearing life by nearly 900%, leading to significant longevity over 3.0×10 6 cycles.
  • In non-cooled conditions, rapid temperature increases led to thermal deformation and visible surface damage after 3.0×10 5 cycles.
  • Rolling contact fatigue tests assessed performance with cooling versus without, under a radial load of 260 N and frequency of 1500 min –1.
  • This research highlights the importance of effective cooling in extending the lifespan of composite bearings in tribological settings.
