Needle roller bearing failure for many reasons, all design and manufacturing processes influencing factors are associated with bearing failure analysis it is not easy to judge. Under normal circumstances, in general, from the use of factors and internal factors to be considered and analyzed. Use the main factors is the installation and adjustment, maintenance, maintenance and repair, such as compliance with the technical requirements. Installation conditions is one of the primary factors in the use of factors bearing often due to improper installation force state changes between the parts of the whole set of bearings, needle roller bearings in the normal state operation and early failure.

According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation bearing to withstand the load, speed, operating temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, to adjust its return to normal. In addition, the quality of the grease and the surrounding medium, the atmosphere analysis and inspection are also important.

How to deal with the effects of needle roller bearings temperature

(1) The alarm bells will ring.

(2) machine next disc water wheels mechanical failure light plate light, the instructions bearing temperature meter temperature increases, the signal relay action.

(3). The thermometer disc (intumescent thermometer) black pin with yellow needle coincidence or exceed the yellow needle.

(4). Issued a needle roller bearing temperature fault signal.

Bearing high temperature phenomenon causes:

(1) of the cooling water may be bearing interrupted, causing high temperatures.

(2) There may be a needle roller bearing oil deterioration, oil itself to unclean or run Zhongyou deterioration. Such as the increase in moisture in the oil will cause the acidity of the oil is increased, will reduce the lubricating effect of the oil, so that the pad of corrosion, thereby causing the phenomenon of the bearing temperature.
