  • Abstract:
    This document presents a curated collection of vintage mid-20th-century advertisements from The Timken Company, a pioneering manufacturer of roller bearings for railroad applications. Compiled by Edwin R. Kraft in December 2024, the collection emphasizes Timken’s promotional campaign for “Roller Freight,” a term highlighting the adoption of roller bearings in freight cars. Drawing exclusively from online sources, the ads illustrate Timken’s strategic efforts to advocate for roller technology as a superior alternative to traditional friction bearings, touting benefits such as reduced rolling resistance, enhanced efficiency, and improved safety. The document serves both as a historical archive and a technical reference, offering insight into the marketing narratives and industrial advancements of the era. It also contributes to ongoing discussions within rail engineering literature regarding the modeling differences between friction and roller bearing systems.
