Vibration of cylindrical roller bearing maintenance

Little local raceways and rolling elements may be damaged. Running, local damage due to handling or installation error. Scroll past the damaged bearing component generates a specific vibration frequency. Vibration frequency analysis of cylindrical roller bearings can identify damaged parts. Application vibration behavior in many application areas, bearing stiffness and rigidity of the structure around the same. Because of this feature, as long as the proper selection of the bearing (including preload and clearance) and its application in the configuration, it is possible to reduce vibrations in the application.
Cylindrical roller bearings of rolling bearing in itself does not produce noise. Usually feel bearing cylindrical roller bearing noise is in fact directly or indirectly from the surrounding structure vibration of sound effects.
Its bearing load of scroll amount may vary slightly in the run, which is why many times noise can be seen as involving the entire vibrations of a cylindrical roller bearing applications. Loaded rolling element changes and generate vibration when a radial load when the load on a bearing. This vibration is not prevented, but through an axial preload to reduce loads on all rolling.
Cylindrical roller bearings consist of a convex spherical outside surface of the inner ring and a corresponding concave spherical surface of outer ring formed. This design is especially suitable for bearing arrangements for the following conditions: must be able to adjust the deviation between shafts and housings, or must be carried out at relatively slow sliding speeds oscillating or recurrent tilting or slewing movements.
Cylindrical roller bearings with sliding contact surface combination of steel on steel. Bearings with the sliding contact surface combination require regular relubrication. This type of sliding surfaces with very high wear resistance, especially suitable for heavy loads, shock loads must be subjected to alternating or heavy static load of the bearing arrangement. Bearings with a cylindrical extension on both sides of the inner ring can be used to replace the bearings on both sides set the General isolation sleeve bearings, or dedicated to the special design of hydraulic cylinder bearings.
