Ball bearings are generally made up of

Ball bearings are generally made up of Correct Answer carbon chrome steel

Explanation:

  • The most common chrome steels contain from 0.5 to 2% chromium and 0.1 to 1.5% carbon. The chrome steel is used for balls, rollers and races for bearings.
  • A Nickel-Chrome steel containing 3.25% nickel, 1.5% chromium and 0.25% carbon is much used for armour plates.
  • Chrome nickel steel is extensively used for motor car crank shafts, axles and gears requiring great strength and hardness.
