Tokyo, Japan, November 9, 2012 - NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that it has developed a super-clean package. It eliminates the need for cleaning and degreasing after opening the packaging of high-precision angular contact ball bearings* designed for such applications as machine tools, and it will contribute to improved quality and productivity. NSK will apply this package to its high-precision angular contact ball bearings starting in April 2013 and is targeting one billion yen in annual sales for 2013.
NSK display the product at the 26th Japan International Machine Tool Fair (JIMTOF 2012), to be held from Thursday, November 1 to Tuesday, November 6 at Tokyo Big Sight (Koto ward, Tokyo).

In recent years, as the need for higher energy conservation and a smaller environmental footprint has grown, the need for grease lubrication has increased, since it is less expensive and easier on the environment than that of oil lubrication. However, compared to oil lubrication, grease lubrication is more susceptible to the accumulation of foreign particles and therefore requires highly clean storage. Traditionally, bearings are packed in anti-rust oil to prevent rust during storage and shipping. However, this means that the machine tool makers must wash the bearing and degrease the anti-rust oil prior to applying lubrication grease to the bearing. However, having such additional processes is counterproductive in terms of assembly time, in addition to the fact that it involves the use of cleaning and degreasing solvents, which are detrimental in terms of their environmental footprint.
In order to answer the need for improved productivity and a reduction of environmental footprint, NSK developed, a super-clean package that eliminates the need for cleaning and degreasing prior to assembly.
