Inserts for sleeve-type bearings

We offer services in production and repair of inserts of sleeve-type bearings with a metal-fluoroplastic covering.

Repair of worn out babbit inserts and replacement of a babbit covering with EMP a covering is possible.

Inserts are delivered ready for installation and operation.

Advantages of inserts with elastic metal-fluoroplastic (EMP) a covering in comparison with babbit:

  • operating life up to 20 years, a warranty period from 18 to 36 months
  • vibration-absorbing properties, decrease of vibration level in bearings
  • low friction coefficient, increase in efficiency factor of the mechanism
  • reliability due to covering structure in case of an emergency situation shaft damage is absent
  • maintainability - the cost of replacement of a sliding support is much cheaper than refilling with babbit
  • significant saving on repairs

The advantages which have been marked out in the information letter of recommendation of "UES of Russia" RJSC No. IP-03-02-00(GP) from 12.04.2000.

  • fast transition from friction at boundary greasing to hydrodynamic (liquid) and, as a result, 3-5 times reduction of friction surface damage at start-up and the shutdown of the rotating mechanism
  • equal adjoining of a center shaft and bearing disk to the run-in fluoroplastic covering which has the polished appearance, even at distortions of the surface of friction or a deviation of a center shaft from a cylindrical form (conicity)
  • practical lack of wear fluoroplastic during the long operation of the bearing in a mode of hydrodynamic greasing with use of the common petroleum turbine oil which has passed through system of cleaning of impurity
  • ability to perceive non-stationary loadings and to extinguish them, transferring impulses to buffer poroelastiñ coating damping dynamic influence shaft train (especially at start-up of the pump, the fan, the smoke exhauster)
  • preservation of regular system of a oil provision and its operating condition, and as standard system of Instruments and Controls
  • decrease in volume of repair work and increase in the turn-around time of operation of the power equipment
