Basic knowledge of rolling bearings that users must know

Whether you want to buy a rolling bearing or use a bearing, you must know some basic knowledge of the rolling bearing. The first is the structure of the bearing. Take the rolling bearing as an example, the inside of the bearing is generally composed of an inner ring, an outer ring, rolling elements and a cage, usually called four part. For sealed bearings, plus lubricant and seals (or dust caps), that's six part.

Let's talk about the working condition of the bearing. When the bearing is rotating, different types of bearings have the ability to bear radial load or axial load. At the same time, radial runout or axial runout will occur. For users, different use environments require different loads and runouts. Only by knowing this can a better bearing be selected.

Different types of bearings are selected according to the specific working environment and requirements of the bearing, so as to better exert the function of the bearing and prolong the service life of the bearing. The factors that need to be considered in the selection of bearings are as follows: radial load, axial load, speed requirements, radial runout, axial runout, working temperature, noise requirements, lubrication conditions, etc., only knowing these will not choose the wrong one bearing.

The above are just some basic knowledge of bearings. In order to choose a suitable bearing, in addition to the knowledge of the user, it is best to consult the bearing supplier, because the bearing supplier has specialized technical personnel, which can provide customers with more accurate choices.
