Deep groove ball bearing type There are many types of bearings, among which deep groove ball bearing belongs to one of centripetal ball bearings. In the process of use, deep groove ball bearing has three characteristics: high speed, high precision and low noise and vibration. It mainly bears radial load. According to the use of…
DetailsIn order to make the deep groove ball bearing get better performance, the general manufacturers will carry out the process processing procedures, which can not only improve the quality of the deep groove ball bearing, but also improve the beauty of the bearing and reduce the degree of friction. In order for you to have…
DetailsDeep groove ball bearing and angular contact ball bearing Deep groove ball bearing and angular contact ball bearing are representative rolling bearings, which are widely used and can bear radial load and bidirectional axial load. They are suitable for high-speed rotation and occasions requiring low noise and low vibration. The sealed bearing with steel plate…
DetailsCommon materials of rolling bearings The inner and outer rings and rolling elements of rolling bearings shall have high hardness, contact fatigue strength, good wear resistance and impact toughness. They are generally made of chromium manganese high carbon steel (anti pitting corrosion). Common materials include GCr15 bearing steel, GCr15SiMn bearing steel, gcr6 bearing steel and…
DetailsReasons for difficult rotation of bearing axis As an important part of mechanical equipment, when we find that the bearing is in operation, the axis of the bearing always feels unable to rotate, that is, the so-called bearing axis is difficult to operate? What’s going on? According to the actual situation, it can be seen…
DetailsHow to choose bearing type Located in Cixi, China, where is one of the biggest bearing manufacturer center in China. There are thousands of bearing factory from big and small.Our place is famous for miniature bearing and precise bearings.We hereby wish to share our experience of choosing suitable bearings. Generally speaking, the steps for selecting…
DetailsInfluence of bearing preload mode and speed There are two ways of axial preload of bearing, one is constant pressure preload, the other is positioning preload. Under constant pressure preloading, with the increase of rotating speed, the radial stiffness of the bearing increases slightly, while the axial and angular stiffness decrease rapidly. Under positioning preload,…
DetailsFactors affecting the service life of rolling bearings Whether in terms of installation or use and maintenance, there are many external factors that will affect the service life of rolling bearings, such as improper installation, improper maintenance and so on. Analysis of installation factors For example, the installation of bearing seat gland and bearing seat…
DetailsInstallation of precision bearing Requirements for matching parts of precision bearings Because the precision of the precision bearing itself is within 1 μ M, so the matching parts (shaft, bearing seat, end cover, retaining ring, etc.) are required to have high dimensional accuracy and shape accuracy, especially the accuracy of the mating surface should be…
Detailsbearing superfinishing process Ultra precision technology is not only used in the bearing industry, but also in the engine. This technology is also used in other precision machinery and instruments. What is bearing superfinishing? Bearing superfinishing process is a finishing method to realize micro grinding by feeding movement. The surface before superfinishing is usually precision…
DetailsThe annealing and normalizing of bearing production Annealing, also known as simmering, code th, is to heat the steel parts above AC1 or AC3 (30 ~ 50 ℃), hold them for a period of time, and then slowly cool them (usually furnace cooling). Normalizing, also known as open fire, code Z, is to heat the…
DetailsAdjustment measures for problems after bearing installation During installation, do not directly hammer the bearing end face and non stressed surface. Use pressure block, sleeve or other installation tools to make the bearing bear uniform force. Do not transmit power for installation through rolling elements. If the mounting surface is coated with lubricating oil, the…
