Sliding bearings are used for the shaft in magnetic coupled centrifugal or displacement pumps. The sliding parts are made of SiC. The pump liquid is circulating between the rotating and static parts to ensure lubrication and cooling. EagleBurgmann LMF bearings are successfully used for many years in applications worldwide. They are almost wearless and therefore extremely durable.


  • Sliding bearing for the shaft of an impeller in a pump
  • Self lubrication through pump liquid
