Suntech® slide bearings are usually designed based on the principle of hydrodynamic lubrication which increases its reliability. When the calculation design and manufacturing conditions permit this type of lubrication, the slide bearings will fulfil all the requirements expected of them.
It has been proven that plain cylindrical bearings built-up its carrying oil wedge by making possible clearance between bearing shell and shaft due to its eccentric position (converging film). Now a days various special geometry design has been implanted which are also based on hydrodynamic calculation as per DIN 31657.

Tilting Pad Journal Bearing operations and it’s limits.

The angle of pad tilt and the maximum film pressure and temperatures are directly take effect on Thrust Bearing operational excellence . The pads leading edge tilts open to provide a converging wedge to produce hydrodynamic load. The resultant load vector passes through the pad pivot

As the maximum pressure is located not at the pad pivot location, but at some angle with rotation from the pivot. Thus, temperature sensors should be placed downstream from the pivot. A good rule-of-thumb is to locate the sensor at the 75 percent position as in Tilting Pad Journal Bearings. That is, at 75 percent of the total pad arc length from the leading edge, Suntech® Designed Tilting Pad Journal Bearings have all required advantages to fulfil all hydrodynamic effect.

Advantage of Suntech® Tilting Pad Journal Bearing.

  • Hydrodynamically stable at high speeds
  • Accommodate varying conditions
  • Less sensitive to load direction or shaft misalignment than fixed profile bearings
  • Optimized lubrication for minimum power loss and pad temperature.
