Single row deep groove ball bearing is the most typical structure of rolling bearing and has a wide range of uses. The raceway in the inner ring and the outer ring is slightly larger than arc cross-section of the radius of the rolling ball.
In addition to withstanding the radial load, it also can withstand the axial load in two directions. Motor torque is small, which is very suitable for the requirements of high speed rotation, low noise and low vibration.
This type of bearing, in addition to the open type, as well as the bearing cover with steel cover, bearing plus rubber seal ring, or bearing with a stop ring on outer diameter of the outer ring .
Generally use steel stamping cage.
Bearing ("Bearing", the Japanese call "shaft") is a component that is used to fix and reduce the friction coefficient during the process of mechanical transmission. It can also be said to be the machine parts which are used to reduce the friction coefficient during power transmission and keep the machine shaft center position fixed when the relative movement occurs on the other parts on the shaft with each other. Bearings are one of the most important share parts in modern mechanical equipment. Its main function is to support the mechanical rotating body in order to reduce the mechanical load friction coefficient during the transmission process. According to the different friction properties of the components, bearings can be divided into two types of rolling bearings and sliding bearings.
It should be supported in terms of its role , that is,the load axis in the literal interpretation. But this is one part of its role and its essence is to support the radial load. It also can be understood that it is used to fix the shaft. It is the fixed axis that only enables it to rotate while controlling its axial and radial movement. The consequences of motor without bearing are not completely to work. Because the shaft may move in any direction and shaft can only rotate when motor works.Speaking theoretically this could not achieve the transmission effect, not only that, the bearing will also affect the transmission.In order to reduce this effect, good lubrication must achieve in the bearings of high speed shaft.Some bearings themselves have some lubrication, which called preliminary lubricated bearings.And most of the bearings must have lubricating oil to load when running at high speed. Because friction will not only increase the energy consumption, more terribly is very easy to damage the bearing. The idea of turning sliding friction into rolling friction is one-sided because there is something called a sliding bearing.
