Product Features of Bearings

  • Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy load
  • Rolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down. However, the bearing capacity is slightly poorer and the vibration resistance is poorer.
