The friction reducer.
Canada’s greatest contribution to the design of modern machines is the roller bearing. Created by George Thomas of Digby County, Nova Scotia, in 1879, the bearing reduces if not eliminates the friction generated by the contact of moving machine parts with stationary ones. The device does so by housing rollers or ball bearings within a roller cage. Today, roller bearings are more important than ever. They are small yet critical components of a variety of devices – from bicycles and cars to farm equipment and industrial machinery. These friction reducers mean smooth running for the world’s machines.
