21 bearing steel market trend middle bearing steel market situation, it is not easy to have very big waves, price stability as the dominant, not prone to ups and downs in the market, the key elements due to the following several aspects.
One is the requirements for bearing steel bearing manufacturing industry chain compressive strength is not easy.
Bearing is low-value mechanical equipment structure.
In addition to adding new projects and increasing machinery goods will drive demand, machinery and equipment goods has promoted the ownership and utilization rate of ascension is to lift the bearing the cost.
With the continuous development of social economy in our country trend continued ascension, automation level, the bearing characteristics, technical standards will also become more and more high, product is multifarious, demand will continue to increase.
By 2015, in the total sales of high-grade bearing casting industry in China will be 222 billion yuan.
2 it is high-end equipment manufacturing in China expanding domestic production of high-grade bearing requirements.
At present, China's general bearing steel can be considering the demand of the market, completed the domestic manufacturing, but high-end equipment manufacturing high-grade bearing also with domestic production to meet the needs of a certain difference, still want to import to fill, such as Angle of touch ball bearings, thrust ball bearings, cylindrical roller bearings bearing and taper roller bearings, bearing the other cars, high-speed train, wind power, high precision lathe spindle supporting facilities bearing has been a high-grade bearing products such as soft to help in the field of bearings in China.
Therefore, high-grade bearing development trend of interior space in our country is very big, broad potential sales market.
Who read this article also browse: bearing is not suitable for adding a variety of grease we know grease has good adhesion, abrasion resistance, heat resistance, non-standard bearing and antirust processing and wettability, can improve the bearing resistance to high temperature oxidation, slow embrittlement, can melt carbon, avoid metal debris and oil gathering, improve mechanical equipment wear resistance, pressure resistance and corrosion resistance.
Understand the lubricating grease in the bearing after exercise process, of course will get a result: the bearing of lubricating oil is not suitable for too much.
Much grease consumption not only, and is influenced.
The higher the speed ratio of the bearing is, the greater the impact.
The greater the distance the more add grease, friction.
Under the same loading, closed type bearing friction torque than open bearings.
When the filling quantity of the grease is equal to the capacity of bearing cavity space, after a 60% without a significant increase in friction torque.
This is because most open grease in the bearing has been extrusion, closed grease in the bearing has lost circulation.
With the increase of amount of grease filling, bearing temperature rise of parallel lines.
Under the same filling amount, closed bearing temperature rise is higher than open bearings.
Think commonly, closed rolling bearing lubrication grease filling amount, shall not exceed the maximum number of interior space to around 50%.
