The solution of TIMKEN bearing temperature is too high

When the bearing temperature is high, the problem should be solved from the following aspects:

(1) The amount of oil added is not appropriate, and the lubricating grease is too little or too much

The bearing box should be oiled regularly in accordance with the requirements of the work. TIMKEN bearings sometimes experience high temperature after refueling, mainly due to excessive refueling. At this time, the phenomenon is that the temperature continues to rise, and after reaching a certain point (usually about 10°C~15°C higher than the normal operating temperature), it will remain unchanged, and then gradually drop.

(2) The grease added to TIMKEN bearings does not meet the requirements or is contaminated

The selection of lubricating grease is improper, it is not easy to form a uniform lubricating film, and it cannot reduce the friction and wear inside the bearing. The lubrication is insufficient and the bearing temperature rises. When different types of grease are mixed, a chemical reaction may occur, causing the grease to deteriorate, agglomerate, and reduce the lubricating effect. Contaminated grease will also increase the temperature of the bearing. Dust will fall into the grease during the process of adding grease, causing grease pollution, resulting in the deterioration of grease in the bearing box, destroying the lubrication of the bearing, and increasing the temperature.
