Seiko (NSK) for industrial pumps used to develop a longer life to the heart of a separate thrust ball bearings, "High Performance Industrial Pump radial thrust ball bearings," which was June 14, 2007 sale. Increased load capacity and lubrication, longer than the company's original product increased by about 50%. Plan out the exhibition in June 2007, held from 27 to 29, "Mechanical Components & Materials Technology Exhibition" (Tokyo Big Sight International Exhibition Center).
Interior design optimized to improve about 13% of the basic dynamic rated load ratio. In this way, due to the use of the same size as when the life expectancy of bearings of 1.5 times, can increase the maintenance interval of industrial pumps and reduce operating costs. In addition, without changing the set life circumstances, through the use of smaller bearings, can achieve the miniaturization of industrial pumps and energy-saving design.
In addition, in order to improve the lubrication in the bearing cage in the adoption of a copper alloy, and on this basis, an improved shape and orientation methods. As the bearing interior space to expand, lubricating oil flows / discharges of been improved, therefore, the bearing temperature rise can be reduced by about 7% - reduced by about 4 ℃. This helps to improve the reliability of industrial pumps. In addition, also increased to an industrial pump assembly when operational. As a result, can more easily ensure that the leaf positioning accuracy of
