The small local bearing raceways and rolling elements may be damaged. In operation, the local damage due to the operation or installation error. Vibration frequency analysis can identify the cylindrical roller bearing parts damaged. The vibration behavior of applications in many applications, the stiffness and the stiffness of the surrounding structure bearing the same. Because of this characteristic, as long as the correct choice of bearings (including preload and clearance) and its application in the configuration, it is possible to reduce the application of vibration.
EDA bearing rolling bearing in itself does not produce noise. Usually feel bearing noise is in fact the sound effects in EDA bearing directly or indirectly with the surrounding structure vibration.
The number of rolling bearing load may vary slightly in operation, which is why many times the noise problem can be regarded as relates to the vibration problem of the cylindrical roller bearing application. Vibration caused by loading the rolling body quantity change when a radial load on a bearing. The resulting vibration is inevitable but can be mitigated by axial pre load, loading on all rolling body.
The bearing ring may be with adjacent components shape matching deformation. If there is deformation, the components of the wave of tight fit between the bearing ring and the bearing or shaft case. Operation may produce vibration. Therefore, the bearing and shaft machined to the required tolerances is very important.
Contact fatigue failure refers to the EDA bearing surface subjected to alternating stress arising from failure. Contact fatigue spalling in bearing surface, often accompanied by fatigue crack, first from the contact surface following the largest alternating shear stress, and then extended to the surface spalling of different shapes, such as point to point pitting or pitting spalling, shallow spalling in the peel into small flakes.

The wear failure refers to the failure of the relative sliding friction between the surfaces due to the surface of metal wear and the. Continuous wear will cause damage to bearing parts gradually, and eventually led to the loss of precision cylindrical roller bearings and other related issues. Wear may affect the shape change, increased clearance and surface morphology changes, may affect the lubricant or its pollution to a certain extent and cause lubrication complete loss of function, so that the cylindrical roller bearing the loss of rotational accuracy and can not operate normally. Wear failure is one of the common failure mode of bearings, according to wear form is usually divided into the abrasive wear and adhesive wear the most common.
1 of the cylindrical roller bearing used in the inner rotating load the correct and the outer ring orbit radial load.
The 2 is the inner and outer rings relative tilt, shaft deflection of the running track, the running track of the raceway surface, in the longitudEDAl produce shading at the exit load ring, orbit is tilted, double row tapered roller bearing inner ring rotation.
3 trajectory of burden radial load of the outer ring. L is expressed only under axial loading at the track. In the inner and outer rings tilted relative big bear radial load situation, its trajectory deviation in two columns of rail surface 180. The location (m).
