Tokyo, Japan, July 20, 2010 — NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) announced today that it has developed a Ball Bearing Equipped with Retainer Plate*1 capable of reducing the total length required for today's automotive transmissions. NSK expects rapidly expanding sales of this advanced new product capable of reducing fuel consumption. NSK is targeting sales of at least one billion yen by 2015.
*1 Retainer Plate: Part designed to secure bearings to the transmission case.
The trend toward greater fuel efficiency of recent years has led to greater demand for more compact transmissions. The new Ball Bearing Equipped with Retainer Plate developed by NSK enables total transmission length to be reduced by approximately 4 mm compared with conventional bearings. As a result, transmissions using this NSK product will be more compact and lightweight, delivering better fuel efficiency.
NSK will aggressively market this product for application in manual transmission (MT) vehicles, which are generating high demand in emerging markets and Europe, and double clutch transmissions (DCT), a popular style of transmission in Europe that combines fuel efficiency with a sporty feel.
NSK will produce this product at manufacturing sites around the world, ensuring worldwide demand is met in a timely manner by shipping from the nearest facility.
NSK uses a sealed configuration designed to prevent gear dust seeping into the ball bearings used inside transmissions. NSK's Ultra Low-friction Sealed Clean Ball Bearings and the High-tough (HTF) Long Life Bearings, which significantly increase product life and reliability, are now widely used by leading automobile manufacturers, both in Japan and around the world.
NSK has achieved compact, lightweight and low torque applications for automobiles by leveraging its four core technologies (tribology, materials, analysis, and mechatronics). The company has been developing these technologies for over 90 years, and is continuing to create products that will improve the fuel efficiency of automobiles.
