Canton, Ohio — The Timken Company has released an enhanced version of its electronic Tapered Roller Bearing Selection Guide compact disc for design engineers. Version 2.0 allows users to analyze bearing selections for new and existing applications, calculate bearing life based on a variety of criteria and save data in electronic, print and/or report form.

Users also can conduct bearing searches for single- or double-row tapered bearings and sort bearing lists based on design criteria such as cone bore or cup outside diameter, dynamic radial load rating, cone or cup width and effective load centre location. The program, which can be run from a number of Microsoft Windows platforms, is available in English, French, German, Italian, Spanish and Swedish.

“We have enhanced this tool to allow engineers to easily calculate the lives of bearings in a two-bearing system,” says Roger Knudsen, vice president – engineering – industrial. “This interactive software is designed to help customers simplify the bearing selection process while providing an alternative to hard-copy catalogues when searching for bearings.”

Users can calculate predicted bearing life within their environments and vary parameters to see how projected life will be affected. The ability to save data eliminates the need to re-key parameters for similar applications and allows designers to share information with others in their organization or with Timken representatives who can provide additional assistance with bearing selection.


The Tapered Roller Bearing Selection Guide was originally released in spring 2001. Popular attributes of the first version have been incorporated into Version 2.0, including an enhanced bearing search function; installation calculations; drawing options that allow users to print or save bearing prints in electronic formats; guidelines regarding the selection process, mounting, lubrication and damage analysis; and reference tables regarding materials and lubricants.

“This guide is a valuable tool for selecting tapered bearings. The ‘Bearing Application’ section is particularly good,” says Chris Peterson, manager of application engineering, power transmission division, at Lufkin Industries, Inc., a manufacturer of oilfield, power transmission, foundry and trailer components. “We now can quickly calculate axial and radial loads and have a consistent way to exchange gear and bearing information with Timken engineers.”

“Version 2.0 is a logical step in the evolution of this tool, which we believe will become a key bearing analysis program for industrial customers around the world,” says Knudsen. “Version 2.0 of the Tapered Roller Selection Guide is the next step in our continuing mission to ease bearing selection and help enhance our customers’ performance.”
