Tapered Roller Bearing History , Applications

History
In 1898, Timken was awarded a patent for the tapered roller bearing. At the time, Timken was a carriage-maker in St. Louis and held three patents for carriage springs. However, it was his patent for tapered roller bearings that allowed his company to become successful.
Tapered roller bearings were a breakthrough at the end of the 19th century because bearings used in wheel axles had not changed much since ancient times. They relied on bearings enclosed in a case that held lubricants. These were called “friction bearings” and depended on lubricants to function. Without proper lubrication, these bearings would fail due to excessive heat caused by friction. Timken was able to significantly reduce the friction on his bearings by using a “cup” and “cone” design incorporating tapered bearings which actually rolled, which reduced the load placed on the bearings by distributing the weight and load evenly across the cups, cones, and bearings.
Applications

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.
Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces.
