About the brand
About Timken
Making tapered roller bearings since 1899.
Henry Timken patented his tapered roller bearing design in 1898, and in 1899 he and his sons, H.H. and William, founded The Timken Company in St. Louis, Missouri, to make it. A few years later the company moved to Canton, Ohio; today it is headquartered in North Canton and has been listed on the New York Stock Exchange since 1922.
A tapered roller bearing has four parts: the cone (inner ring), the cup (outer ring), the tapered rollers and the cage. The cone, rollers and cage stay together as the cone assembly and separate from the cup, so cones and cups have their own part numbers and are sold alone or as a set. The tapered design carries radial and thrust loads together.
In 2003 Timken bought The Torrington Company, a leading maker of needle roller bearings, from Ingersoll-Rand. Timken also makes ball bearings and housed units under the Fafnir name, which introduced the wide inner ring ball bearing in the early 1900s.
