Polymer Bearings

Polymer-lined thrust bearings can expand bearing operating limits and increase reliability compared to conventional babbitted bearings. Engineered polymers use bearing grade materials to improve self-lubrication and heat dissipation, allowing polymer bearings to operate with thinner hydrodynamic films and at higher temperatures.

Engineered polymers also provide excellent embedability, corrosion resistance and anti-galling properties to prevent damage and extend bearing life.

 

Typical Applications

  • Downhole pumps – operation with high loads and high temperatures
  • Gas turbines – to withstand heat soak without the need for back-up lubrication 
  • ORC turbines – to sustain the thin films associated with the low-viscosity working fluid/lubricant
  • Water- and process-lubricated pumps, motors and compressors
  • High speed and high temperature applications with limited oil cooling
  • Machines with sump or non-circulating lubrication
