Q. The material used in the production of bearing is
A. Cast iron
B. Babbitt metal
C. Pig Iron
D. Steel
Answer: Babbitt Metal
Babbitt, also called Babbitt metal or bearing metal, is any of several alloys used for the bearing surface in a plain bearing.
The alloy mentioned in the patent was 89% Tin, 9% Antimony and 2% Copper, which is amazingly close to today's very popular ASTM B-23 Grade 2 “Babbitt” was originally applied to Tin-base alloys, it is now used to describe bearing metals with lead or other metals as the major element.

Babbitt metal is a metal that has very little friction. It is used for bearings. It can be made from tin, copper, antimony, or lead. Normally it is a certain mixture of these metals. It is very soft. There are harder and softer parts in it, though. This creates small holes where grease can go in when the soft parts rub away. An item with bearings could be a fidget spinner or a bicycle wheel.
