Affect the life of deep groove ball bearing analysis of the factors

Deep groove ball bearing material largely determines the bearing life, once the metallurgical quality bearing steel GCr15 early bearing failure is caused by the most important reason. Technically increased dramatically in the metallurgical, bearing steel and other materials have appeared, has been greatly improved.
 In bearing failure analysis, from raw material bearing failure caused the proportion has also been greatly improved, but is still manufacturing materials main bearing failure, but also with deep groove ball bearing service life considerably relations.

 Bearing complex manufacturing process, to go through several processes before they can get the finished product, including forging, heat treatment, turning and grinding and other processes to complete the technical ability and quality, will affect the bearing life and apply effects, especially heat treatment and grinding process, it is the direct cause of many bearing failures, manufacturers need to be highly valued.
 deep groove ball bearing after installation, in order to check the installation is not correct, you want to run checks. Small machines can be rotated by hand to make sure is not rotate smoothly. Check items mainly due to foreign bodies, indentation caused by dysfunctional, because poor installation, mount poor processing and the emergence of torque instability, because clearance is too small, the installation error, caused by seal friction torque is too large, and so . If no exception, you can begin powering.
 On the shaft and bearing, the bearing requirements in the radial, axial and tangential direction in three directions fix its position. Radial and tangential positioning through the tight fit of the bearing rings mining achieve axial positioning only in a few cases, a tight fit; generally use limit axial parts, such as end caps and rings etc. is limited to the axial position In the clearance range.
     Select match should focus on the following four points:
   (A) the bearing rings and the circumferential surface should be well supported even by force, in order to reduce distortion, and give full play to the bearing capacity.
   (2) In its mating surface of the ferrule can not slide along the tangential direction, otherwise it will damage the mating surfaces.
   (3) the free end of the shaft and the bearing must be capable of bearing adapt to changes in length of the hole, which must have to adapt to the axial position in a range of swimming ability.
   (4) must pay attention to the deep groove ball bearing mounting and dismounting is simple, saving time and labor costs.
