High carbon chromium bearing steel is usually used for the ferrule and rolling body.CCr15 is used for most bearings, and CCrl5SiMn with good hardenability is used for bearing rings with large sections and rolling bodies with large diameters.High carbon chromium bearing steel is an integral hardened steel, its surface and heart can be hardened, is the best material for rolling bearings.

The role of rolling bearing is to transform the sliding friction between shaft and shaft seat into rolling friction. In the process of rolling bearing operation, rolling friction will cause bearing heating and wear. In order to reduce friction and damage, rolling bearing operation needs lubrication.

The high bearing capacity of roller bearings makes its application very wide. The design and processing of rollers are also developing continuously.A new type of tapered barrel roller bearing will be introduced below.

Cross roller bearing is a sub-industry in bearing classification.There are many different kinds of cross roller bearings according to different standards. XSU series is a basic series with large market usage. This paper takes XSU series as an example to explain in detail.

Bearing is one of the important "joint" of mechanical equipment, once bought fake goods bearing, can bring a lot of damage to machinery and equipment, if a large mechanical equipment because of fake goods bearing for repair, the losses during the basic is nearly ten thousand yuan, in order to let everyone know about fake goods bearing more, today to share some distinguish fake goods bearing techniques.What are the main characteristics of counterfeit bearings?What are the means of bearing fraud?How to distinguish true and false bearings?I hope it helps.

Therefore, please fully study the installation of bearings, that is, please carry out the installation of bearings in accordance with the operating standards including the following items

Bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, crack, wear and so on will be reflected in the bearing vibration measurement, so, by using a special bearing vibration measurement device (frequency analyzer, etc.) can measure the size of vibration, through the frequency can not infer the specific situation of abnormal.The measured values are different due to the use conditions of bearings or the installation position of sensors, etc., so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.

The change to the drum, also known as the guide drum, is a common key part of the belt conveyor, mainly used to change the direction of the conveyor belt or pressure the conveyor belt to increase the Angle of the transmission drum.

Thrust ball bearing belongs to the separation type bearing, including a shaft ring (with the journal), a seat ring (with the bearing seat) and a group of steel ball and cage composition.When installing, it can be easily matched with the journal and bearing seat respectively.

The inner and outer rings of tapered roller bearings have tapered raceways, and the rollers are also tapered.If the tapered surface is extended, its vertex intersects at a point on the bearing axis.Therefore, the roller of tapered roller bearings can achieve pure rolling on the raceway.

Cylindrical roller bearing belongs to the separation type bearing, it is very convenient to install and disassemble.Cylindrical roller bearings can bear large radial loads and are suitable for use at high speed.

When choosing standard slewing bearing, we should pay attention to three problems, namely, load, bolt strength, and whether there is a uniform bolt hole. These three conditions are essential.Here is a detailed and comprehensive understanding of it.

Tapered roller bearing can bear radial and axial load at the same time. It is composed of two outer rings, one spacer ring and one inner sleeve assembly.Bearing manufacturing clearance has been adjusted with spacers according to user working conditions and national standards when the products leave the factory. Users only need to install it according to the correct operating procedures.

Robot bearings are a kind of bearings used in industrial robots. They are generally used as joint parts of bearings. The commonly used robot bearings are cross roller bearings and equal section thin-walled bearings.No matter what kind of bearing robot is in use, there are many matters needing attention. Today, I will tell you about the use of robot bearings.

1 bearing design structure comparison of special vibration bearings: A. The diameter of the rolling body is increased, the length of the rolling body is increased.B. The cage is guided by the outer ring to reduce the force on the roller.C. Use inner ring to guide the roller and improve the operation of the roller.
