bearing 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…

The 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…

Adjustment 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…

Factors affecting the life of bearing steel The comprehensive sign of the internal quality of bearing steel is the fatigue life. Some scholars put forward the view that reducing the oxygen content has not yet played a role in greatly improving the fatigue life of bearing steel. In fact, only by reducing the content of…

Digital brain update bearing industry Recently, the Department of economy and information technology of Zhejiang Province announced the list of the first batch of pilot projects for industrial brain construction, and the brains of bearing industry and smart home appliance industry jointly built by Cixi City of Ningbo were on the list. With the help…
DetailsGrease lubricated or oil lubricated Rolling bearings are widely used in industrial production and are the basic accessories of mechanical equipment. The function of rolling bearing is to convert the sliding friction between shaft and shaft seat into rolling friction. During the operation of rolling bearing, rolling friction will cause bearing temperature rise and wear.…

The fit between the bearing and bearing seat hole When selecting a bearing fit, the various factors discussed in this section should be considered, as well as the general selection methods provided. Rotation condition The rotation condition refers to the movement condition of the bearing ring relative to the load direction. There are basically three…

Classification Of Bearings Bearings are divided into two categories: sliding bearings and rolling bearings Sliding bearing Sliding bearings, bearings that work under sliding friction. The sliding bearing works smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surface is separated by lubricating oil without direct contact, and friction loss and surface wear can…

The reason for bearing runs hot Rolling bearing “hot” is often encountered in production. If the cause is not clear, the treatment is not timely, and the measures are not appropriate, it will often get twice the result with half the effort, and may even cause vicious accidents such as bearing burnout and gear…

Bearing tolerance class Bearings under the ABEC system are generally called precision bearings, with numbers from 1 to 9. The higher the number, the higher the accuracy level for bearing manufacturing（ Large = narrower tolerance zone range = more expensive price). What does the tolerance zone mean? Tolerance zone refers to a series of the…

The characteristics, differences and uses of the fourteen types of bearings Bearings are divided into radial bearings and thrust bearings according to the nominal contact angle of the bearing direction. According to the type of rolling element, it is divided into: ball bearing and roller bearing. According to whether it can be adjusted, it is…
