NSK Bearings in order to ensure the normal operation and long, the need for regular maintenance and repair of the bearing.
Typically, if used correctly NSK Bearings, you can use to reach the fatigue life so far. But there will be accidental injury prematurely, not resistant to the use situation. This early damage, and fatigue life relative, called the quality of failure or accident use limit. Multiple causes for installation, use, pay attention on the lubrication from outside intrusion of foreign matter, the shaft, the thermal effect of the housing is not sufficient and so on.
NSK bearing damage on the state, such as: roller bearing ring wall card injury, may be considered as a reason to lack of lubricant, not suitable for oil discharge structure defects, foreign invasion, bearing misalignment, shaft torsion curved too large, there will be overlap of these reasons.
Therefore, only the investigation bearing damage, injury is difficult to know the real reason. However, if you know the use of mechanical bearings, conditions of use, bearing the surrounding structure, to understand the situation before and after the accident, combined with NSK bearing damage state, and several reasons, we can prevent similar incidents from recurring.
Bearing fatigue life test is adequate lubrication, maximum inhibition of bearing wear, and increased capacity and speed, to highlight factors NSK bearing fatigue life test method for enhancing the fatigue. In most cases, it is based on mechanical or other design limitations. The type and size of the bearing, so the choice of the decision is based on the bearing diameter.
NSK Bearings Manufacturing will go through forging, heat treatment, turning, grinding and assembly of multi-channel process operation. Reasonable handling, advanced, will also affect the stability of the bearing life. Influence of heat treatment and grinding bearings, bearing failure is often associated with a more direct relationship related to product quality. In recent years, research deterioration of the surface layer of the bearing that the grinding process is closely associated with the bearing surface quality. Bearing fatigue life calculation and fatigue life test are complementary, the two results is adequate correspondence, therefore, the bearing life test is necessary or important, in most cases, in the case before use, a standard calculation method, the estimated life of the bearing life, there is adequate level of reliability.
NSK bearing life factors, there may be many, from the use of factors and internal factors further instructions. The main factor is used to adjust the installation, use and maintenance, maintenance, etc. meet the technical requirements. According to the bearing installation, use, maintenance, maintenance of the technical requirements in contact bearings operating load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to adjust it back to normal.
