Guide: there are imported guide wheels and export guide wheels on the wire rod mill. The guide wheel bearing is a high-speed light load bearing with a linear speed of 96 meters/second and a required service life of 72 hours. Therefore, it is widely used, and domestic steel enterprises use imported bearings. Wazhou group organized engineering and technical personnel to go deep into the steel industry users, to wire rod

there are inlet guide wheels and outlet guide wheels on the wire rod mill. The guide wheel bearing is a high-speed light load bearing with a linear speed of 96 meters/second and a required service life of 72 hours. Therefore, the amount of use is very large. The required cylinder is placed in the groove, and the domestic steel enterprises use imported bearings. Wazhou group organized engineers and technicians to go deep into the users of the steel industry to develop the high-speed bearing of the guide wheel of the wire rod mill. At present, a variety of specifications of bearings have been developed, and the sample trial production has been completed and passed the test, which has been recognized by the users

the automobile retarder is the auxiliary braking device of the vehicle, which undertakes about 30% - 80% of the braking energy required when the vehicle decelerates, so as to avoid braking failure caused by excessive brake temperature or tire burst caused by excessive friction, and enhance the safety of vehicle braking. The development and research of the bearing for the retarder of the axle acceleration vehicle. The retarder bearing provided for users has passed the test of 40000 km sports car, and is currently undergoing bench test

the world's largest overweight mobile combined crane under construction in China is 11 times the lifting capacity of the largest mobile crane at present, which is used for the construction of offshore drilling platforms. The bearing of the supporting pulley block of the crane is developed synchronously, and it is successfully matched for users

affected by the downward economic boom at home and abroad, the development of machinery industry this year continued the downward trend of growth rate in 2012. Facing the severe market situation, Wazhou group accelerated structural adjustment, took the research and development of major equipment precision bearings as the direction, took precision technology and manufacturing as the support, implemented the commanding height strategy, constantly achieved major breakthroughs and mass production in high-end bearing products, and drove market growth with high-end products. In the first half of this year, it completed the research and development of 450 new products

at present, the bearing group has preliminarily mastered the functions of 4. The test results of this machine can be stored, transferred, compared, analyzed and printed out. It has carried out the core and key technologies of bearing research and development, carried out the multidisciplinary basic research of bearing structural mechanics, Materialogy, lubrication and friction, vibration and noise, reliability test and so on, mastered the high-end bearing design, manufacturing and testing technology supporting major technical equipment, and built wind power generation The five product test platforms of rail transit, large equipment, automobiles, machine tools, etc. have solved the core technologies of high speed, high precision, long life and sealing lubrication in the application of bearings in many fields. From a single bearing manufacturing factory to an innovative enterprise with technical solutions, they have shown an exceptionally prosperous market, and have changed the key technical equipment in many key fields of our country. High precision, high reliability The long-term dependence on imports of high-speed bearings provides a strong guarantee for the rapid development of China's major complete equipment manufacturing industry

in the research and development of high-end bearings, the bearing shaft successfully developed 10000rpm ultra-high speed spindle bearings in the first half of the year to replace imports and develop new markets; Complete the research and development of the main rotating bearing of medical CT machine and realize the replacement of import; Successfully developed high-speed wire rod mill bearings in the iron and steel industry to replace imports; Realize the replacement of imports of high-end gearbox bearings and high-end motor bearings, and mass production. In addition, new breakthroughs have been made in the research and development of high-end bearings in ships, aviation and so on

by implementing the commanding height strategy, Wazhou group has comprehensively improved the accuracy standard and service life standard of bearing products, and comprehensively reduced the application cost of equipment. The maintenance free period of railway bearings has been increased from 4 years to 8 years, the maintenance free period of automobile bearings has reached 300000 kilometers, the reliability of wind power generation bearings has reached 20 years without failure, and the localization of supporting bearings in the metallurgical industry has reached the level of similar foreign products
