History of Roller Bearing

Bearing is a device that use in relative motion between two or more parts, typically for rotation or linear motion. Classification of bearing can be explained according to motions, principles and operation that they allows and as well the directions of applied load that handle.

Roller bearing invented as in the form of moving on wooden rollers as an object, a great ancientness and may precede to the invention of wheel, Egyptians used the roller bearing as tree trunks under sleds i.e. modern speculation, their own drawing describes that in the tomb hypothesis as moving stone blocks on sledgehammers using running lubricated a liquid which would establishes a plain bearing.

In the early stage, bearing is a wooden ball bearing supporting a rotating table from the remains of the Roman Nemi ships.
