Double row deep groove ball bearings

 Double row deep groove ball bearings in the use of the process, if used improperly or improper maintenance of some cases, it is highly likely double row deep groove ball backing bearings damage.
If the double row deep groove ball bearings are well lubricated and properly debris and moisture barrier, which means that there should be no oil seal wear. However, the best in the open double row deep groove ball bearing box, check the double row deep groove ball bearings and regularly check seals, check near the double row deep groove ball bearing oil seal at the situation in order to ensure that they are adequate to prevent hot liquid or corrosion liquid or gaseous infiltration along the axis double row deep groove ball bearings, oil seals If wear should be replaced soon.
Temperature often represents a double row deep groove ball bearings in unusual circumstances, high temperature also harmful in the double row deep groove ball bearing lubricant, and sometimes double row deep groove ball bearing overheating can be attributed to double row deep groove ball bearing lubricant If the double row deep groove ball bearings in more than 125 degrees Celsius long run, will reduce the double row deep groove ball bearing life.
High double row deep groove ball bearings causes of damage include: lack of lubrication or excessive lubrication, the lubricant containing magazine, the load is too large, double row deep groove ball bearing damage, lack of space, and the heat generated by friction seals and so on.
Double row deep groove ball bearing 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 double row deep groove ball bearing load is too large, this fatigue worse. In addition, double row deep groove ball bearing is not properly installed, the shaft bent, will produce raceway spalling. Double row deep groove ball bearing raceway fatigue spalling will reduce shaft running accuracy, enables organizations to vibrate 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.
Burns its double row deep groove ball bearing raceways, rolling on the temper color. The reason is usually burns insufficient lubrication, oil quality does not meet the requirements or deterioration, and the double row deep groove ball bearing assembly tight and so on.
Double row deep groove ball bearing raceway and roller contact surface uneven pits, indicating double row deep groove ball bearing plastic deformation. The reason is that double row deep groove ball bearings in a large static load or impact loads, the working surface of the local stress exceeds the material yield limit, which generally occurs in low-speed rotation of the double row deep groove ball bearings.
Double row deep groove ball bearing ring cracks may be due to double row deep groove ball bearings with tight, double row deep groove ball bearing foreign or inner loose, double row deep groove ball bearings of tolerance deformation, installing double row deep groove ball bearings and poor surface finish. Double row deep groove ball bearing cage fragmentation, the reason is a double row deep groove ball bearings insufficient lubrication, rolling broken seat skew and so on.
