Tapered roller bearings are separable bearings, bearing inner and outer rings with tapered raceways line. These bearings are mounted on roller rows into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load

it is highly likely to occur cylindrical roller bearing damage.
Cylindrical roller bearings in the use of the process, if used improperly or improper maintenance of some cases, it is highly likely to occur cylindrical roller bearing damage.
Cylindrical roller bearings lubricated if get good and correct debris and moisture barrier, which means that there should be no oil seal wear. However, the best in the open cylindrical roller bearing box, check the cylindrical roller bearings and regularly check seals, check near the cylindrical roller bearing oil seal at the situation in order to ensure that they are adequate to prevent hot liquids or corrosive liquids or gases along the axis Heart penetrate cylindrical roller bearings, oil seals If wear should be replaced soon.
Temperature frequently expressed cylindrical roller bearings in unusual circumstances, high temperature also harmful in the cylindrical roller bearing lubricant, sometimes cylindrical roller bearings overheating can be attributed to cylindrical roller bearings lubricant, if cylindrical roller bearings in more than 125 degrees Celsius long run, will reduce the cylindrical roller bearing life.Cylindrical roller bearing high temperature causes of damage include: lack of lubrication or excessive lubrication, the lubricant containing magazine, the load is too large, cylindrical roller bearing damage, lack of space, and seal the heat generated by friction and so on.
Cylindrical roller bearings rolling elements and the inner and outer raceway surfaces are exposed to periodic pulsating action of the load, resulting in a periodic variation of contact stress. When stress cycles reaches a certain value, the rolling elements or inner, outer ring raceway fatigue spalling on the work surface. If the cylindrical roller bearing load is too large, this fatigue worse. In addition, the cylindrical roller bearing is not properly installed, the shaft bent, will produce raceway spalling. Cylindrical roller bearing raceway fatigue spalling will reduce shaft running accuracy, enables organizations to happen vibration and noise. Adhesion of the metal cage on the rolling elements, may cause the rolling body is within the card in the holder or insufficient lubrication.
Cylindrical roller bearings burns its raceway, rolling on the temper color. The reason is usually burns insufficient lubrication, oil quality does not meet the requirements or deterioration, and cylindrical roller bearing assembly tight and so on.
