The cage is designed that the number of needle rollers and the needle roller length can be increased while maintaining the same bearing dimensions. The larger number of rolling elements and the increase in their loadbearing length means that the load ratings of new -D needle roller bearings in X-life quality are up to 25 % higher. The bearings installed in the same mounting space can be subjected to significantly higher loads. Viewed another way, the new -D needle roller bearings in X-life quality open up new design options for downsizing, i.e. a reduction in the size of machines and units while maintaining the same performance. For example: The X-life needle roller bearing NK20/16-D with a bore diameter of 20 mm and a width of 16 mm corresponds to the existing X-life needle roller bearing NK26/16 with a bore diameter of 26 mm in terms of load carry capacity. If the new bearing is used for downsizing, the section height of the bearing is reduced by 15 %, the weight by 20 % and the friction by 30 % while maintaining the same load carrying capacity. www.schaeffler.com About Company name: Schaeffler Technologies Brands: INA, LuK and FAG Headquarters: Herzogenaurach, Germany Turnover: € 11,2 bn (2013) Employees: over 79,000 worldwide Products: Rolling bearing and plain bearing solutions, linear and direct drive technology, as well as high-precision products for the automotive industry 32 MDA Technologies 4/2014
