Are you familiar with deep groove ball bearing? If not, this article will help you broaden your horizons. Here you can get an overview of this bearing. Generally speaking, deep groove ball bearings often consist of a pair of rings, a set of cages and a set of rigid spheres. Its model code is 6, which is a very common bearing. The bearing is simple in structure and easy to use, and is widely used in various equipments.
Deep groove ball bearings mainly bear pure radial loads. At the same time it also bears radial and axial loads. When it is only subjected to pure radial load, the contact angle is zero. When the bearing has a wider radial clearance, it acquires the properties of a contact angle bearing and bears a larger axial load. Compared with other bearings of the same size, the friction coefficient of this bearing is extremely small and the limit speed is fast. Especially in the case of very large axial load, it has advantages over thrust ball bearings. After the bearing is installed on the shaft, the displacement of the shaft can be controlled within the range of the axial clearance.
Because the bearing has a simple structure and is easy to achieve high manufacturing precision, mass production is quite convenient. Depending on the structure, there are many deep groove ball bearings such as deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, and deep groove ball bearings with snaps. Although they have some differences, they all share the following characteristics. First, structurally, each ferrule has a continuous grooved raceway with a cross-section about one-third of the circumference of the sphere. The function of the raceway is to support radial and axial loads. Secondly, as the radial clearance increases, the bearing can support the axial bearing that changes in two different directions. Third, the friction is low, but the revs are high. Last but not least, stamped wave retainers are often used.
