For precision industrial applications, Seiko has developed a long-life single-row radial thrust ball bearing "High-performance radial thrust ball bearing for industrial pumps", which was launched on June 14, 2007. Increased load capacity and lubricity, and life expectancy increased by approximately 50% compared to the company's original products. It is planned to exhibit the "Mechanical Element Technology Exhibition" (Tokyo Ariake International Convention and Exhibition Center) held on June 27-29, 2007.
The internal design has been optimized to increase the basic dynamic load rating ratio of approximately 13%. In this way, since the life of the bearing of the same size is extended by 1.5 times, the maintenance interval of the industrial pump can be increased, and the running cost can be reduced. In addition, the industrial pump can be miniaturized and energy-saving by using a smaller bearing without changing the set life.
In addition, in order to improve the lubricity, a copper alloy is used in the bearing cage, and the shape and the guiding manner are improved on the basis of this. Due to the expansion of the internal space of the bearing, the inflow/discharge of the lubricating oil is improved, so that the temperature rise of the bearing can be reduced by about 7% - by about 4 ° C. This helps to increase the reliability of industrial pumps.
In addition, the operability when assembled into an industrial pump is also improved. Thereby, the positioning accuracy of the industrial pump blade can be more easily ensured. The price is negotiable.
