Damper support bearings

Since 1990, damper bearings have been successfully used in the most critical compressors, turbines, gas compressor units, pumps, and multipliers with high reliability requirements.

Meets the requirements of API 617 standard.

The existing range of bearings covers a range of shaft diameters from 40 mm to 500 mm with rotor speeds from 1,500 rpm to 40,000 rpm.

By agreement with the customer, it is possible to develop and manufacture a bearing that differs from the existing series for specified geometric parameters, load-bearing capacity and rotor speed.

Support bearings are the most important components that ensure the stability of rotor rotation in modern high-speed machines: compressors, gas turbines, turbogenerators, multipliers, pumps, etc. In critical positions, it is important to use bearings that can not only withstand self-excited vibrations, but also dampen vibrations for stable expansion working range.

Advantages:

  • high damping capacity, reduction in vibration level by 1.5 – 3 times (6 -10 times in starting and unsteady modes)
  • high load-bearing capacity
  • reduced shaft precession and no wear of radial seal surfaces due to the absence of rotor-housing contact
  • stabilization of rotor dynamics, reducing the consequences of emergency situations
  • stability of clearances (no rotor subsidence phenomenon)
  • built-in protector against electrical erosion destruction
  • do not require replacement of the oil system, the standard one is used
  • long service life
  • increase in overhaul mileage to 6 years
  • compactness, high maintainability.
