For rolling bearings, we know that there are many types. According to the main load bearing direction of the rolling shaft, they are mainly divided into radial bearings and thrust bearings . Radial bearings can withstand loads perpendicular to the shaft. Some radial bearings can only carry pure radial loads, while most radial bearings can also withstand axial loads in the same direction, and in some cases, axial...

When assembling the thrust ball bearing , attention should be paid to distinguish between the tight ring and the loose ring. The tight ring and the shaft are fitted tightly and are relatively stationary with the shaft. The inner hole of the loose ring is larger than the inner hole of the tight ring, and it is a clearance fit with the shaft. After assembly, the tight ring should rest on the plane of the rota...

Bearing steel is the steel used to make balls, rollers, and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel grades in all...

Bearings must be installed in dry, clean ambient conditions. Before installation, the machining quality of the mating surfaces of the shaft and the housing, the end faces of the shoulders, the grooves and the connecting surfaces should be carefully checked. All mating surfaces must be carefully cleaned and deburred, and unmachined surfaces of castings must be free of residual molding sand. Before the b...

Angular contact ball bearings are not necessarily used in pairs. The angular bearing is also called a radial thrust bearing. The structure is that the bearing rollers form a fixed angle with the axis, thereby generating both centripetal force and axial force, which can also play the role of centering and bearing. It is equivalent to installing a plane bearing and an ordinary cylindrical bearing at t...

LBCN BEARING offers  ANGULAR CONTACT BEARING , including single row, double row and high temperature series. 1. Represents different AC is the code of the domestic bearing; A is the angle code of the Japanese bearing; C is the angle code of the Japanese bearing. 2.

Bearings are common parts and key parts in industrial equipment, and the application of bearings is also very common. In order to make money, many businesses recycle some old bearings that have been used or have not been used as new bearings to buy. Today, LBCN Bearing will share with you how to identify whether the bearings are refurbished bearings when purchasing bearings. 1. Refurbishment of bearings is ...

There are many methods for positioning and fixing the inner and outer rings of rolling bearings . The following are several commonly used methods: a) The shaft retaining ring is embedded in the groove of the shaft, which is mainly used when the axial force is not large and the rotation speed is not high: b) The shaft end retaining ring fixed with screws is fastened, which can be used to withstand large axial ...

Tapered roller bearings are suitable for radial loads, unidirectional axial loads and combined radial and axial loads. The axial load capacity of tapered roller bearings depends on the contact angle , that is, the angle of the outer ring raceway. The larger the contact angle , the greater the axial load capacity. Generally, tapered roller bearings are not allowed to have angle error, but the surface of the ...

The outer ring and rolling elements of angular contact ball bearings should have high hardness and contact fatigue strength, good wear resistance and impact toughness. - Generally made of chromium-manganese high carbon steel (anti-pitting corrosion), commonly used materials are GCr15 bearing steel, GCr15SIMn bearing steel, GCF6 bearing steel, GC9 bearing steel, etc. The hardness after quenching is not les...

In the manufacturing process of needle roller bearing parts, various defects may occur after forging, rolling, punching, turning, grinding, heat treatment and other processes. The following are five common defects in the manufacturing process of needle roller bearings. 1. Forging defects  Forging wrinkles are easy to form wrinkles on the surface due to uneven cutting, burrs, burrs and ot...

When the cylindrical roller bearing is disassembled and inspected, the failure of the bearing and the cause of the damage can be judged according to the damage of the bearing. 1. Metal peeling on the raceway surface The rolling elements of the bearing and the raceway surfaces of the inner and outer rings are subjected to periodic pulsating loads, resulting in cyclically varying contact stress. When t...

The failure phenomenon of cylindrical roller bearings is generally manifested in two types, one is that the temperature of the bearing installation part is too high, and the other is that there is noise in the operation of the bearing. 1. The bearing temperature is too high When the mechanism is running, the part where the bearing is installed is allowed to have a certain temp...

Ltd ., was founded in 1995 ,is a trade enterprise specializing in design, production, manufacturing, bearing sales and service.We can offer ODM/OEM service,produce according to your samples or drawings.Looking forward to making business with you. ASK: Why do needle roller bearings need axial positioning ANSWER:  Needl...

Many motors in industrial applications are large motors, such as power plants, steel mills, large-megawatt wind turbines, etc., so this article focuses on the bearing configuration of large motors and spherical roller bearings used in large motors Roller thrust bearing expertise. 1. Bearing configuration of large motors The main function of the bearing is to transmit the load while rotating, so whether it i...

Due to the different types, structures, tolerance levels, technical requirements, materials and batches of rolling bearings, their basic production processes are not exactly the same. LBCN Bearing will show something about the process of rolling bearing . 1. The processing process of the ferrule: The processing of the inner ring and the outer ring of the bearing varies depending on the raw material or th...

Different methods are adopted according to different parts. Based on past experience, the following conclusions are drawn:     1. Remove the outer ring.   Remove the outer ring of interference fit, set several screw for extrusion screw of outer ring on the circumference of outer shell beforehand, tighten the screw equally on one side, and disassemble at th...

When many people install the cylindrical bearing, the bearing is damaged due to the wrong installation method and cannot work normally. Therefore, LBCN emphasizes here that the correct installation method of the cylindrical bearing is a very important part.There are two common ways of correct installation of cylindrical bearings: one is cold installation and the other is hot installation. cold install ...

Bearings need to be maintained and maintained irregularly during the use process. Even so, some failures will not be avoided during the use of bearings. We better repair the use of bearings.
