The role of ZZ series bearing coordination and selection skills

The role of the zz series bearing is to make the stationary ring and rotating ring of the bearing solidify with the stationary part (usually the bearing seat) and the rotating part (usually the shaft) of the installation part, so as to realize the load transfer and the rotation in the rotating state. The basic task of defining the position of a moving system relative to a stationary system. On the shaft and in the bearing seat, rolling bearings are required to fix their positions in three directions: radial, axial and tangential directions. Radial and tangential positioning is achieved by tight fitting of zz series bearing rings. Axial positioning is only used in a few cases with tight fitting; generally axial limiting parts, such as end caps and retaining rings, are used to limit the axial position Within the clearance range.

The zz series bearing is an important part of machinery. It can also be said to be a mechanical joint. Just like us humans, it won't work if there is no joint. If a person has no joint, it will be paralyzed. What is the role? Then it is useless. The same is true for machinery. Without the zz series bearing, the machinery cannot be used. Therefore, the machinery cannot be separated from the bearing. Without the bearing, it cannot survive, which is equivalent to a waste product. The use of zz series bearing is very complicated. Some rolling bearings need to be used in conjunction. This knowledge that ordinary technicians only know, we ordinary people must not know it. Let’s introduce the use and requirements of this rolling bearing. , And also know the basics for you to be familiar with bearings in the future.

The following four points should be paid attention to when choosing cooperation:

The circumferential surface of the zz series bearing ring should have good support and uniform force to reduce deformation and give full play to the bearing capacity. The ferrule cannot slide in the tangential direction on its mating surface, otherwise the mating surface will be damaged. The free-end zz series bearing must be able to adapt to the change in the length of the shaft and the bearing seat hole, that is, it must have the ability to adapt to the axial position to swim within a certain range. Attention must be paid to make the bearing installation and disassembly simple, saving labor, time and expenditure.
