What Are The Various Types Of Bearings?

1 Answer

Answer :

 Bush Bearing. It is a plain cylindrical bearing made of brass , gun metal ,cast iron etc. Its inner bore is finished and made running fit to the shaft. It is generally used on low speed shafts carrying light load.
 Ball bearing. It consists of outer race, inner race, steel balls and cage. The balls are rolling themselves in the tracks between the outer and inner races ,bearing is fitted on shaft while its outer portion is fixed in housing .Balls have point contact and are free in the races,friction makes balls to rotate.
