Just in case you missed this page, it's a little more detailed.
"Simi Valley, CA (August 23, 2005) - Innovative Turbo Systems® announced today the development of their new patent pending "Super Duplex" Dual Ball Bearing Technology.
The Super Duplex bearing system is provided for use in high speed rotating machinery such as a turbocharger, wherein a turbocharger rotor-group supported by a pair of angular contact bearings subjected to radial and a predetermined and substantially constant thrust pre-load. The angular contact bearings are carried respectively within a pair of cylindrical bearing sleeves that cooperatively define an axially split bearing carrier mounted within a center housing. A pre-load element and a hydraulic load react between these bearing sleeves for applying a substantially constant axial thrust pre-load transmitted by the bearing carriers to the angular contact bearings.
The Super Duplex bearing system, scheduled to be released 3rd quarter of 2006, is highly anticipated in the turbocharger industry as the first in a string of new technologies from Innovative Turbo Systems.
The Super Duplex Bearing System significantly improves bearing life, operational stability, and adaptation to thermal growth of turbocharger components during transient system operation.
"The Super Duplex Bearing system is cutting-edge turbo-machinery technology," says Robert McKeirnan, Vice President of Engineering, Innovative Turbo Systems®. "Innovative built its reputation by leading the industry, this new technology continues that tradition."
"This bearing system will serve as the foundation for several complimentary technologies and will ensure Innovative´s continued success," says Ola Lysenstoen, we are very exited about the "Super Duplex." We expect to be shipping turbo products containing the Super Duplex technology during 3rd quarter 2006. "
I can wait a year or two for the new BB's to be proven in Buicks.
