Burns its double row deep groove ball bearing raceways

Double row deep groove ball clutch 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.
