This article is Part III in a series of articles on speed rating of bearings. Part I appeared in the September 2022 issue ("Ball Bearing Limiting Speeds"), and Part II appeared in the October 2022 issue ("Ball Bearing Thermal Speed Rating"). Bearings with Norm examines the latest in bearing technology and design. 

Vesconite Bearings, through its supply of marine rudder bearings to the MN Colibri charter vessel in June, is proud to be associated with an exciting communication satellite launch that took place in September 2022. The MN Colibri has historically transported launcher components, including communications satellites, for various heavy-lift space launch vehicles, and outfitted with the Vesconite rudder bearings allowed it to transport the Eutelsat Konnect VHTS satellite, which is regarded as an important addition to global telecommunications infrastructure.

The Timken Company has acquired the assets of American Roller Bearing Company (ARB), a North Carolina-based manufacturer of industrial bearings. ARB's offerings join Timken's industry-leading portfolio of engineered bearing solutions. ARB, which boasts a large U.S. installed base and strong aftermarket business, generated sales of more than $30 million in 2022.

With the new SKF Bearing App for the popular Ansys Mechanical Finite Element Analysis (FEA) software, engineers no longer need to rely on approximations or complex, unreliable models in their simulations. 

Next-generation technology—everything from the electrification of vehicles to e-motors, bearings, mechatronics, and thermal management—was discussed during the Schaeffler Symposium 2022 in Detroit. I sat down with Jitesh Modi, director of engineering, during the event to discuss the “reinvention” of bearings for EV applications.

Rolling bearing life depends on the contact stresses that occur between the rolling elements and the raceways. Contact stresses are calculated from contact loads, which in turn depend on the external loads acting on the bearing and the precise internal geometry of the bearing.

The PTDA Foundation, whose work is funded solely by donations, was founded in 1982. Its core purpose is to champion education, outreach and research initiatives relevant to the PT/MC industry that enhance the knowledge and/or professionalism and productivity of industry stakeholders.

The Timken Company has completed its previously announced acquisition of GGB Bearings.
