the Cylindrical roller bearing highest export price

the deep groove ball bearing ball into the outlet occupies 7
This year, two months before export Luoyang Bearing 10 categories , a total of 724,000 units. Exports deep groove ball ball 521,000 units, an increase of 21 %, accounting for 71.9% of total tapered roller bearing bearing 105,000 units, an increase of 0.9 % over the same period exports accounted for 14.5% of bearings as well : angular contact ball bearing bearing 37,000 units, 24,000 units of other ball bearing , needle roller bearings 16000 sets.
Fourth, the drum-shaped Tapered roller bearings  highest export price
This year, two months before Luoyang drum-shaped roller bearings export average price of 430.8 yuan each , cylindrical roller bearings average price of 390.6 yuan each , but exports were only 01,500 units and 02,700 units, compared with the average export price products with high export volume is low. The ball bearing deep groove ball average price 7.8 yuan each , the lowest average export price of products, the highest export volume .
The past two years largely maintained Luoyang Bearing exports about $ 200 million . Luoyang Bearing exports Stainless steel slewing bearing substantially from miniature bearings , Luoyang Bearing micro level of technical quality of products have been close to international standards , has occupied a stable international market . However, high-end products bearing the lag contain the development of the entire bearing industry . Since the end Luoyang Bearing in performance and price ratio, high precision, low noise, long life and high reliability and foreign well-known enterprises there is a big gap , reflected in the market is the domestic demand for high-end bearings are still to be rely on imports to meet . Therefore , in order to maintain long-term Luoyang Bearing Industry level in a steady and rapid development , the focus should be placed on top of the R & D and industrialization of high-end bearings .

Cylindrical roller bearing is a kind of modern machinery and equipment vital components

Bearing components are fixed and reduce the coefficient of friction in the mechanical load transmission process. When the other parts in the movement of the shaft relative to each other tapered roller bearings during the power transmission to reduce friction coefficient and to maintain a fixed position of the shaft center parts . Bearing is a kind of modern machinery and equipment vital components. Its main function is to support the rotating body for reducing the mechanical transmission device of the mechanical load during the friction coefficient .
China is one of the earliest countries in the world in our ancient invention Rolling constructed on the axle bearings has long been documented . Bearing is an important foundation for all types of machinery and equipment spare parts to its accuracy, performance , life and reliability of the host precision , performance , longevity and reliability play a decisive role . Bearing in mechanical products are precision products requires not thrust ball bearing only a comprehensive support mathematics , theoretical physics and many other disciplines and require materials science , heat treatment technology, precision machining and measurement technology , digital technology and efficient numerical methods and powerful computer technology and many other So bearing disciplines to serve on behalf of the National Science and Technology is a powerful product . Development momentum of China's manufacturing industry, a strong bearing on the smooth bearing steel market will bring positive effects to the good

the Roller Bearing seal forms affected by the following factors

In order to prevent dust and moisture from entering the bearing to avoid loss of the lubricant in the bearing must be sealed. In general, the bearing seal forms affected by the following factors :
⑴ bearing outside the work environment ;
⑵ bearing speed and temperature ;
⑶ support structure and characteristics of the shaft ;
⑷ lubricant types and performance .
Sealed in accordance with the principle can be divided into two categories : Automotive Lubricants non-contact seals and contact seals . Non-contact seal unrestricted rate . Lower Tapered roller bearing speeds where you can use the online contact seals , commonly used materials with fine felt, rubber, leather , cork or antifriction good hard materials.
Rolling bearing lubricants manufacturers, the main role of the lubricant is to reduce friction and reduce wear resistance , while also reducing the contact stress , to avoid corrosion , vibration absorption , cooling , heat and so on.
Grease and oil lubricated are commonly used in two ways lubrication . Further , in some special cases it is Roller bearing possible Cylindrical roller bearing  to select the lubricating solid lubricants . Which way to use a lubricant , and the speed of the relevant bearing , the rolling bearing is usually used in measuring the speed dn value represents the size of the bearing .
Greased loss is not easy , simple structure, easy to seal and maintain, operate in a long time , just to fill a grease . Fill generally not exceed the amount of grease to one half of the third bearing grease filling too easily lead to friction and heat , affecting the normal performance of the bearing. Smaller than greased friction , heat dissipation, is the main advantage of oil lubrication , so the lubricating oil is mainly used for high-speed or high temperature applications.
