Polymer Thrust Bearings
Polymer-lined thrust bearings can expand bearing operating limits and increase reliability compared to babbitt 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.
Polymer-lined bearings can serve as direct replacements for babbitt components or be incorporated into new designs to extend operating limits.
Technical Data
- Loads up to 10 MPa (1500 psi)
- Temperatures up to 250°C (482°F)
- Operation with low-viscosity lubricants
- Corrosion resistant
- Embedability similar to babbitt’s
- Electrical insulation
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
- Motors and generators – to prevent damaging currents from passing through the bearing and housing
