About The Timken Company
Using This Catalog
The Timken Company was founded in St. Louis in 1899 by Henry Timken with his patented design for the tapered roller bearing. Five generations of Timken family members have led the company as it developed an ever-increasing number of tapered roller bearing designs and applications. In 1917, the company entered the steel business to ensure an uninterrupted supply of bearing-quality steel. Through international acquisitions in the 1990’s, the company expanded its product offering to include other bearing types, including ball bearings, and cylindrical and spherical roller bearings. Timken’s acquisition of The Torrington Company in 2003 combined two organizations sharing a very similar heritage, brand promise and market approach. Both companies have demonstrated traditions of quality, technology and innovation. Further, both have earned the respect of their customers due to a collaborative, customer-centric approach to identifying and implementing solutions. Through the acquisition, Timken is providing a broader range of friction-management products and services. Timken has expanded its position as a leading global manufacturer of alloy steel and tapered and needle roller bearings for the aerospace, automotive, industrial and rail markets. Specifically, its industry credentials now include:
