First, what is bearing preloading? The pre-tightening of rolling bearings refers to the initial pressure and pre-deformation generated between the rolling body of the bearing and the inner and outer rings during the installation of the bearing, so as to keep the inner and outer rings of the bearing in the state of compaction and...

The assembly of rolling bearings should be determined according to the structure, size and mating nature of bearing components. General assembly methods of rolling bearings include hammer method, compression method, hot loading method and cold shrinking method, etc. 1, the preparation work before the assembly of rolling bearings...

1. Why do bearings have thrust clearance and expansion clearance? A) Metal materials have the properties of thermal expansion and cold contraction. When the shaft is operated at different temperature conditions, the length and diameter of the shaft will also change. Therefore, in order to ensure the formation of pressure oil fil...

The reducer is a kind of rotating equipment, and the bearing plays a very important role in the rotation of the equipment. Therefore, the installation and detection of the bearing are very important when the reducer is in use. In the process of use, some common problems of reducer bearings are also the problem of everyones relat...

1. Basis for choosing cooperation According to the load acting on the agents bearing relative to the rotation of the ferrule, there are three types of loads borne by the ferrule: partial load, cyclic load, and swing load. Generally, cyclic load (rotating load) and swing load adopt tight fit; except for special requirements in us...

Cylindrical roller bearings are generally only used to bear radial loads. Only single-row bearings with ribs on the inner and outer rings can bear smaller directional axial loads or larger gap axial loads. What is bearing load? Bearing load is the load received by the bearing during use, including lateral load and longitudinal l...

The assembly of rolling bearings should be determined according to the structure, size and mating nature of bearing components. General assembly methods of rolling bearings include hammer method, compression method, hot loading method and cold shrinking method, etc. 1, the preparation work before the assembly of rolling bearings...

Deep groove ball bearings have a variety of sealing structures. According to the different sealing materials, they are mainly divided into two types: rubber sealing ring and dust cover (standard iron cover): according to different seals, they can be divided into contact sealing and non-contacting. seal. For sealed deep groove ba...

At present, deep groove ball bearings used in motorcycles, home appliances motors and luxury ceiling fans industries usually design different sealing structures according to the mounting position or working conditions of the bearing. For example, the single-sided sealed motorcycle engine case bearing is lubricated by splash lubr...
