Deep Groove Ball Bearings

The original list of deep groove ball bearings, radial ball bearings, is the most widely used type of rolling bearing. It is characterized by low frictional resistance and high rotational speed. It can also be used on parts that bear axial loads, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

Basic parameters

Deep groove ball bearings are the most common type of rolling bearing.

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open types. There are two types of structures, open type means that the bearing does not have a sealing structure, and the sealed deep groove ball is divided into dust-proof seal and oil-proof seal. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

Working principle

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.

Bearing characteristics

Deep groove ball bearing is the most commonly used rolling bearing, its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear the combined radial and axial load. It can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a small friction coefficient and high limit speed, but it is not resistant to impact and is not suitable for bearing heavy loads.

Bearing structure

Compared with other types, the deep groove ball bearing has a simple structure and is easy to achieve higher manufacturing accuracy, so it is convenient for mass production in series, and the manufacturing cost is also low, and it is extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with retaining grooves, and Deep groove ball bearings with large load capacity of ball notches, double row deep groove ball bearings.
