subject: All about Deep Groove Ball Bearings [print this page] There are various kinds of ball bearings such as angular contact ball bearings, ceramic ball bearings, self-aligning ball bearings and deep groove ball bearings, etc. Among all these different categories, the deep groove ball bearing is the most common type. The basic model of this product consists of an outer ring, an inner ring, steel balls and cages.
The structure of the deep groove ball bearings is quite simple. It is very easy to use them. Moreover, it is a kind of bearing product which has the largest production volume and wide range of applications. They are mainly used to bear radial load, meanwhile, they can also bear some axial load. When the radial internal clearance of bearing is enlarged, these bearings have features of angular contact ball bearings and they can bear larger axial load. Compared to other kinds of bearings which have the same size with them, the deep groove ball bearing has smaller coefficient of friction and higher rotation speed. Besides, this kind of bearing can replace thrust ball bearings to support axial loads under very high rotation speed.
When deep groove ball bearings are installed in the shaft, they can limit the axial displacement of the shaft or housing in both directions within the axial clearance. Therefore, they can make axial positioning in two directions. Additionally, this type of bearing has a certain ability of aligning. Most of their cages are steel stamping ribbon cages.
The manufacturing costs of deep groove ball bearings are relatively low. In addition to basic models of deep groove ball bearings, there are still many others such as deep groove ball bearings with dust cover, deep groove ball bearings with a rubber seal ring and double row deep groove ball bearings, etc.
There are many advantages of this kind of bearing products. Firstly, they are suitable for high speed and high rotation operation. Secondly, they are very durable even without regular maintenance. Thirdly, they have small friction coefficient and low costs of manufacturing. Fourthly, they have various sizes and models which can meet different requirements.
Like many other kinds of bearings, deep groove ball bearings also have a wide range of applications such as gearboxes, instruments, motors, pumps, household appliances, internal combustion engines, agricultural machinery, construction machinery, and engineering machinery.
