Roller Bearing Characteristics

 Bearing is a support shaft parts, it can guide the rotation of axis, it also can be subject to turn over the shaft parts, bearings can be divided into the rolling bearing and sliding bearing, generally speaking the bearing refers to the rolling bearing. The rolling bearing change the sliding friction into rolling friction between the operation axis and shaft block, and reduce the friction loss of a precision mechanical components.

  The advantages and disadvantages of rolling bearing: 
  Merits: 1.small friction resistance, small power consumption, high mechanical efficiency, easy to start;
  2, size standardization, interchangeable, easy to installation and unload, convenient maintenance;
  3, compact structure, light weight, more narrow axial dimensions;
  4, high precision, high speed, small wear, long life.
  5, part of the bearing have Self-aligning performance;
  6, suitable for mass production, stable and reliable quality, and high production efficiency.
  Faults: 1,big  noise; 2,complicated bearing structure; 3,high cost
