Ball bearing races are

Ball bearing races are Correct Answer Lapped

There are four major parts to a standard ball bearing: the outer race, the rolling balls, the inner race, and the cage.

  • The surfaces where the bearing fits into the machine must be very round, and the sides must be flat.
  • The surface that the balls roll on is ground first, and then lapped.
  • This means that a very fine abrasive slurry is used to polish the races for several hours to get almost a mirror finish.
  • At this point, the races are finished, and ready to be put together with the balls.

Compare the values of the two quantities in the question and answer. Quantity 1: A bag contains 20 balls which are red, green and blue. Find the number of red balls in the bag, if the probability of picking a blue ball is 2/5 and that of either a red or a blue ball is 3/4.
