Rolling bearing is used for roll neck metallurgy, mining and other rolling rack, roller bearings used. Usually cylindrical roller bearings under radial load, deep groove ball bearings or angular contact ball bearings, thrust or radial design or design of the tapered roller bearing axial load. Now they use oil mist lubrication oil lubrication or lubrication and cooling bearing manner.
Oil film bearing technology, is a systems engineering technology, and also the multidisciplinary field of comprehensive engineering technology, its development speed and ability to support the formation of a reflection of the pace of development of Chinese industry and the level achieved. The early 1950s, China's Anshan Iron and Steel cold rolling mill only reversing mill equipped with an oil film bearings. Its operation and management, in full accordance with the relevant regulations of the Soviet Union was. The traditional process, the pressure is not rolling, rolling speed is low, the lubrication system is also very simple, run skill levels are relatively low. But in actual operation, the relevant management and technical personnel and operating workers work very seriously, in strict accordance with procedures to do, accumulated use, maintenance experience.
However, due to a lack of understanding of the bearing works, some of the less reasonable procedures has been followed for almost two years, for example, installed after the bearing member, to do the pressure test 35N / cm2, if the oil spill, which tighten rotary seals, until no leakage so far. However, such a pressure test after adjustment, use the effect is not good, but, seal life is short. This seal is with the skeleton of "J" type seal, is to rely on lip sealed immediately after the pressure test tone, it is no longer lips sealed, but a ribbon cling to the surface of the rotary seal. But after all fundamental, successfully run oil film bearing, or start from here. In the early 1960s put into operation oil film bearing our own equipment in order to Wuyang Iron and Steel Company 4200mm plate mill φ1300mm special roll film bearing, φ300mm frame roll film bearing and Benxi Iron and Steel Company φ1700mm hot rolling mill oil film bearing support rollers as represented φ1100mm a number of new bearings put into operation, the former is a single rack rolling mill, which is a multi-stand tandem mill.
Several multi-stand rolling mill oil film bearings in operation, so that our run oil film bearing technology to popularize and improve. On the management side, has a professional technical personnel and skilled workers, a dedicated workplace, the workplace be closed oil film bearing oil film bearing maintenance personnel, lubrication personnel have clear job responsibilities and procedures, the increasing division of labor Fine, management more scientific and standardized. Since the update of the bearing structure improvement and lubrication system on bearing installation and lubrication systems maintenance operations, than the 1950s we have made great progress, coupled with the successful use of rolling mill oil film bearing, so run to the modern technical level and a step closer.
70 to 80 years, China has successively set to introduce in the Wuhan Iron and Steel Company 1700mm hot, cold plate rolling mill and Shanghai Baoshan Iron and Steel Plant of 2050mm and 2030mm hot, cold plate rolling mill at the same time, also will be set to introduce a Mogeyier (MORGOIL) bearing and 麦斯塔 (MESTA) bearing, the main operating personnel, including technical personnel, skilled workers have carried out job training, and after the equipment into operation, but also to ensure continuous safe operation of the bearing, which marks Our oil film bearing operation technology, has been close to the level prevailing in the world.
Since the 1990s, and the introduction of complete sets of mill and rolling mill oil film bearings - mainly Mogeyier bearings, and more when buying second-hand rolling equipment, but also into the oil film bearings, the main types are Mount Geyi Er bearings. Thus, in some of the major types of mills, such as wire rod mill, single stand reversing mill, semi-rolling mill, rolling mill and section mill are all equipped with the film bearing; from the bearing type, liquid-friction bearings Soviet Union, China TZ brand film bearing, the United States Mai Sita film bearings and Mogeyier (film) bearing, can be regarded as the world's most complete variety of countries with rolling mill oil film bearings (including lubrication system). According to incomplete statistics, China has two dozen Iron and Steel Company (plant), equipped with nearly 200 mill bearing oil film, can not that huge quantity. This case illustrates the operation of the mill oil film bearing technology has been widely spread in China, and has reached a new level in today's world.
As a key metallurgy, rolling mill industry supporting bearing, rolling mill bearing manufacturing level represents a level of manufacturing large and extra large bearings countries, many countries have mill bearing manufacturing technology on a very important position in-depth study. Similarly, the emerging industrial city of Luoyang after the establishment of China is one of the first industrial cities in China focused on building a five-year plan, is the eldest son of a true republic. After 60 years of construction, Luoyang has formed a relatively complete industrial system, the city's economic growth rate of the industrial economy as high as 74%. Five pillar industries of equipment manufacturing, energy, electricity,

petrochemicals, new materials, silicon photovoltaic and optoelectronics account the proportion of the total above-scale industries reached 71.5%, Luoyang Bearing Manufacturing Technology also played a role in the domestic bearing industry leader. As Luoyang Bearing mill specializing in the production development of enterprises, the Department of Engineering Limited Luoyang Bearing Technology is a large, extra large bearing design, manufacture, research and development, sales as one of the specialized Limited. The company formerly known as the Department of labor large Luoyang Bearing Manufacturing Co., was established in 1998 to produce casting, cold-rolled, hot-rolling mill bearings and high precision foil rolling bearings is known, is the most mature and most advanced rolling bearing manufacturer, after ten years of effort, Luoyang Department workers' access to continuous casting and rolling mill roll neck bearing support means rolling bearing dust removal devices and other six patented technologies. Henan University of Science and became the first private partners and teaching practice base in 2008, the scientific applications using characteristics of the bearing, lubrication, torque, noise, heat and other aspects of the production practice. Our products passed the ISO9001: 2008 quality management system certification. Export products according to customer requirements, third party testing SGS, DNV, ABS, ASIA and other international testing organizations. The Department is currently working to maintain steady development of bearings and increase the export efforts, it has formed a industrial scale. Excavators, cranes and other vessels with a wheel bearing, casting, cold-rolled, hot-rolling mill bearings and high precision foil rolling mill bearings, as well as thin-walled bearings, military bearing have been successfully developed to achieve a stable supply of acceptance; successfully developed Several highly sophisticated bearing, highly praised by users.
Compared with similar imported bearings, domestic mill bearing not only has considerable technical level and higher quality assurance and price advantage is more obvious. The Department currently has a large number of workers bearing well-known brand customers, products exported to the United States, Japan, India, Spain and more than thirty countries and regions, sales increased year after breakthrough, steadily increased.
