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.

Rolling bearing is the most widely used in rotary machinery, and it is also one of the most easily damaged components.Many failures of rotating machinery are related to rolling bearings. The working quality of bearings has a great impact on the working state of machinery. The defects will lead to abnormal vibration and noise of equipment, and even damage the equipment in serious cases.Correct condition monitoring and diagnosis of rolling bearings is an important aspect of equipment optimization management and predictive maintenance in modern enterprises.

The spalling at the limit position of the single side of the channel is mainly manifested in the serious spalling belt at the junction of the channel and the retaining edge.The reason is that the bearing is not installed in place or sudden axial overload in the process of operation.The countermeasures are to ensure that the bearing is installed in place or the outer ring fit of the free side bearing is changed to a clearance fit, in order to compensate the bearing when the bearing is overloaded.If it is impossible to ensure that the installation is in place, the oil film thickness of the lubricant can be increased (to improve the viscosity of the lubricant), or the load of the bearing can be reduced to reduce the direct contact of the bearing.

Under a certain load, the number of revolutions or hours experienced by the bearing before pitting is called the bearing life.

Whether the bearing is correctly installed is related to the service life of the bearing, so we must pay attention to the following Longteng bearing to introduce the five steps of the correct installation of the bearing in detail. I hope it will be helpful to you who are using the bearing.

Four rows of cylindrical roller bearings and six rows of cylindrical roller bearings are almost all used in the roll neck, roller and rolling machine of the steel rolling frame.These bearings have low friction compared with other roller bearings.Because these bearings are usually mounted on the roll neck with interference fit, they are particularly suitable for rolling mill applications with high rolling speed.The low cross section of these bearings allows the use of a relatively large roll neck diameter compared to the roll diameter.Due to the large number of rollers, the radial load capacity is very high.

Railway locomotive and rolling stock bearings refer to bearings used in locomotives and rolling stock.On the locomotive bearing including axle box bearings, bearings, traction motor bearings, transmission system power plant bearing and the bearing of the cooling system, etc, and the bearing on the railway vehicle is the main axle box bearings, passenger car axle box multi-purpose short cylindrical roller bearing, truck axle box mainly adopts circular cone roller bearings, varieties, structure, performance of these vehicles bearing are similar to those of locomotive axle box bearing basic.

Characterized by large area, shallow depth, easy to find.The main reason for this rust is that there is moisture, dust and gases such as SO2, H2S, CO2 in the atmosphere. In hot and humid conditions in summer, especially in places with large air flow, the peripheral of bearing stacking is prone to this rust.

Bearing position wear of roller press is a common equipment fault in the process of roller press operation. What causes bearing position wear of roller press?
