Deep Groove Ball Bearing Advantages and Disadvantages

The most frequently used bearing is the deep ball bearing. It is found in almost all kinds of product in general mechanical engineering. In this type of bearing, the radius if the ball is slightly less than the radii if curvature of the grooves in the races. Kinematic ally, this gives a point contact between the balls and the races. As a result, there will be no sleeping and the balls and races are rolls freely. 

The Advantages of Deep Groove Ball Bearing are as follows:

  1. Due to relatively large size of the balls, deep ball bearing has high load carrying capacity.
  2. A deep groove ball bearing can withstand axial and radial loads.
    Because of point contact, deep groove ball bearings produce less noise.
  3. Deep groove ball bearing  are available with bore diameter from a few millimeters to 400 millimeters.
  4. This bearing experiences less frictional loss and subsequent temperature rise because of the point contact between the balls and races. The maximum speed of shaft is determined by the temperature rise of the bearing. Thus, Deep groove ball bearings are used for high speed applications. 

The Disadvantages of Deep Groove Ball Bearing  are as follows:

  1. Deep groove ball bearing  is not self aligning. It is necessary to line the shaft's axis accurately with the housing bore.
  2. When compared to roller bearings, deep groove ball bearings are less rigid. This is due to the print contact compared with the line contact in case of roller bearing. For machine tool spindles, where rigidity is a key factor, it is incorrect.
