TIMKEN 663/653 bearing

Bearing 663/653

The company traces its roots back to the time Henry Timken applied a tapered roller bearing design to heavy freight wagons that had a problem making sharp turns. Timken's invention could handle both cornering force and radial loads that provided several customer benefits such as improved wagon performance and smooth running.
