The most commonly used oil bearing is powder metallurgy oil bearing.Through the preparation of powder, forming, sintering and impregnation of lubricating oil and other major processes made of bushing is called powder metallurgy oil bearing.Then how to calculate the powder weight of powder metallurgy oil-bearing bearing?

Bearing as an important part of the operation of mechanical equipment, when we find that the bearing in the process of operation, the shaft of the bearing always feels not moving, that is, the so-called bearing shaft operation is difficult?What's going on here?

Question 1: Will bearing steel rust? Will rust.Bearing steel, including stainless steel, rusts. Although stainless steel is known as stainless, it is also rusty, in fact, there is no stainless steel in the world!

Steel market trend wide rising over this week, this week timber prices constantly refresh historical thread, thermal highest volume exceeding RMB 6200 and 6700 respectively, the market continued to pull up, scrap steel market traders want to stay up, the arrival of the goods volume did not significantly improve individual traders actively delivery on Thursday, prices fell slightly, price falls present state on Friday,Steel mills today are 91 down, 0 up.

Since the festival, the steel market as a whole industry has risen in an all-round way, a number of varieties of goods is set nearly 10 new high prices.According to data, as of May 11, steel mining industry chain, spot price, iron ore up 49.19%, billet up 46.75%, rebar up 34.9%, wire up 36.11%, hot rolled plate coil up 46.87%, seamless pipe up 26.87%, stainless steel plate up 5.89%, profile overall up 5.69%.

Bearing is an important part of modern mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure the accuracy of rotation.Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage.According to the shape of the rolling body, rolling bearings are divided into ball bearings and roller bearings.Although there are many types of rolling bearings, and there are differences in their structural types, tolerance levels, material selection and processing methods, the basic manufacturing process is similar. The following is a brief introduction to the processing technology of bearing parts:

Rolling mill bearings are used in the calendering industry, namely the calendering of nonferrous metals, ferrous metals and nonmetallic products.Used for bearing at roll diameter and roller of calendering roll system.Usually, four rows of cylindrical roller bearings are used to bear radial load, thrust roller or thrust ball bearings and centripetal angular contact ball or centripetal roller bearings are used to bear axial load. Now, most of them are lubricated by oil and gas lubrication or oil mist lubrication and grease.

On April 27, 2021, China Iron and Steel Association (CISA) released the first-quarter operation situation of the steel industry.According to the report, China's steel production in the first quarter overall stable, output maintained year-on-year growth.

Bearing arrangements for the air handling industry Bearings arrangements for compressors, fans and centrifuges must meet very high requirements related to functional reliability and cost reduction.In most cases, standard bearings can meet the requirements, while special bearings are required in some applications.In order to minimize the pressure loss caused by the clearance in the compressor, the guiding clearance of the rolling bearing arrangement is required to be very small.Some compressors operate at very high speeds, so special attention needs to be paid to the speed capacity of bearings.In the compressor, four point contact ball bearings, cylindrical roller bearings and angular contact ball bearings are mainly used.

Bearing is an important part of a fishing wheel.It has the function of overcoming the transmission resistance, under the condition of ensuring that the receiving line is blocked, the fishing line wheel can rotate smoothly and smoothly, overcome the noise of mechanical friction during the transmission, and make the fishing wheel more smooth.

Bearing is an important part of modern mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure the accuracy of rotation.The following is the competition analysis of the bearing industry.

Bearing temperature standard - pump bearing temperature standard During the operation of the pump, the highest temperature of the bearing shall not exceed 80℃ 3.2.9.2 Bearing temperature rise shall not exceed ambient temperature 40, and the highest temperature shall not exceed 80℃ 4.3.3 When the pump is running under specified working conditions, the temperature of the outer surface of the inner bearing should not be 20℃ higher than the temperature of the conveying medium, and the highest temperature should not be higher than 80℃.The temperature rise of the outer surface of the external mounted bearing should not be 40℃.The highest temperature is not higher than 80℃ 4, JB/T7255 5.15.3 service temperature of bearing.The bearing temperature rise shall not exceed the ambient temperature of 35℃, and the highest temperature shall not exceed 75℃ The bearing temperature rise shall not exceed the ambient temperature of 40℃, and the highest temperature shall not exceed 80℃ Bearing temperature rise shall not exce

What is the difference between plastic bearings and metal bearings?The difference in material use of bearing products is divided into plastic and metal categories. Although the basic function is the same in actual work, it can be seen that there are still great differences between the two kinds of bearing products.You can distinguish it from the following:

On the vibration of bearings, many technicians have different views.Therefore, it is difficult to say that there is a correct comparison. Today, we will share with you the cause of bearing vibration.

Oscillating screen roll bearing is used for mining, vibrating screen machinery, vibration motor, bearing plays an important role in our life.
