Plain bearings for thermal management

The alternative to carbon graphite bearings in coolant pumps and valves

With the continuing trend towards BEV, PHEV and HEV, the importance of thermal management (TM) is increasing and with it the demands on the systems. igus offers the right bearing for various TM applications such as water pumps and cooling water manufacturers and will be happy to support you in your selection.

Bearing requirements in TM applications:

  • Resistance to water-glycol
  • Temperatures up to 150°C
  • No leakage over service life
  • Resistant to contamination from moulding sand


Advantages of igus plain bearings:

  • Cost advantages over carbon graphite, PTFE and ceramic bearings
  • Quiet operation
  • Up to 80% weight savings
  • Ideally suited in combination with plastic shafts
  • Overmoulding possible
Markus Feth, Head of Automotive iglidur Bearing Technology, explains the advantages of iglidur plain bearings compared to carbon graphite bearings in coolant pumps.
