Deep groove ball bearings primarily support radial loads, but can also support both radial and axial loads. When supporting only radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they exhibit the properties of angular contact bearings and can support large axial loads. Deep groove ball bearings also have a low coefficient of friction and a high maximum speed.
Bearing Characteristics
Deep groove ball bearings are the most commonly used rolling bearings. They have a simple structure and are easy to use. They are primarily designed to support radial loads, but when the radial clearance is increased, they exhibit some of the properties of angular contact ball bearings and can support combined radial and axial loads. They can also be used to support pure axial loads at higher speeds where thrust ball bearings are not suitable. Compared to other bearing types of the same size, these bearings have a lower coefficient of friction and a higher maximum speed. However, they are less impact-resistant and unsuitable for heavy loads.
When mounted on a shaft, deep groove ball bearings limit axial displacement of the shaft or housing in both directions within the bearing's axial clearance, thus enabling axial positioning in both directions. In addition, this type of bearing has a certain self-aligning ability. When it is tilted 2' to 10' relative to the housing hole, it can still work normally, but it has a certain impact on the bearing life.
