Deep groove ball bearing material largely determine the bearing life, once GCr15 bearing steel metallurgical quality is caused by failure of the early Rolling most important reason. In the metallurgical technology dramatically, bearing steel and other materials have appeared after, has been greatly improved. In bearing failure analysis, the proportion of bearing failure caused by the raw material has also been greatly improved, but the manufacturing material remains the leading cause of bearing failure, but also with deep groove ball bearing life has a significant relationship.

Bearing complex manufacturing process, to go through several processes before they can get the finished product, including technical capability of forging, heat treatment, turning and grinding processes and complete quality will affect the life of the bearing and application of results, in particular, heat treatment and grinding process, it is the direct cause of many bearing failures, it is necessary to get the company's attention.

Deep groove ball bearings after installation, in order to check the installation is not correct, check to be run. Small machines can be rotated by hand to determine the rotation is not smooth. Check projects are dysfunctional due to foreign bodies, indentation caused due to poor installation, poor mount process and the emergence of unstable torque, the torque due to clearance is too small, installation error, caused by seal friction is too large, etc. . Without exception, you can start powering.

The shaft and the bearing housing, the bearing requires a fixed position in three directions radial, axial and tangential direction. Radial and tangential positioning through the tight fit of the bearing rings achieve mining, axial positioning only in a few cases were a tight fit; commonly used axial spacing parts, such as end caps and the axial position of the collar and other limited within the clearance range.

Should be chosen with the focus on the following four points:

(1) the peripheral surface of the bearing rings should have good support and even by force, to reduce the distortion, and give full play to the carrying capacity of the bearing.

(2) rings can not slide in its mating surface in a tangential direction, otherwise it will damage the mating surfaces.

(3) the free end of the bearing must be able to change the length of the shaft and the bearing hole adapt, which must have the ability to accommodate axial position within a range of swimming.

(4) must pay attention to the deep groove ball bearing installation and removal easy, saving time saving time and labor costs.
