Recently, Luoyang Bearing Research Institute(LBRI) has passed professional examination of the national key project that they had taken the responsibility for. The projects include developing high precision, long service time ball bearings suitable for the ultra high or low temperature condition; developing small turbo pump bearings and precision miniature bearings for the frame of gyro accelerometer.
Among the three new products, the first high precision and long service life ball bearings were designed for the high speed gyro motor, which always work in the ultra high or low temperature conditions. This ball bearings developed by LBRI has reached P4 precision level and proved to be satisfactory in the course of customers' trial run.
Since it founded in 1958, Luoyang Bearing Research Institute(LBRI) has been the only state institute in Chinese bearing industry. In 1999, LBRI were changed from a non-profit state-run organization to a independent enterprise.
They mainly engaged in developing and researching bearing theory, design, equipments, material, measuring methods etc. Meanwhile, they are able to carry out trial or mass production of precision bearings, special bearings, bearing measuring tools and other related machine tools. They also have a listed subsidiary, Luoyang Bearing Science & Technology Co.,Ltd. "ZYS" are their registered band.
