Tilting pad journal bearings

Tilting pad journal beaings are used in many applications in turbo machines.
One important advantage of these bearings is very good applicability for high surface speed.

Another advantages

  • hydrodynamic stability in high surface speed
  • low sensitivity to load direction
  • low sensitivity to shaft misalignment
  • minimizing of oil flow

These bearings can be designed in wide range of variation on the basis of hydrodynamic calculation.

GTW tilting pad journal bearings are designed as folows:

  • 5 tilting pads
  • directed lubrication
  • standard seal
  • variable design of bearings seating
  • design for both directions of speed

Bearings are produced in range of diameter sizes: 35mm to 500 mm.
