250 kilowatts of motors, replacement of new bearings, after driving bearing fever, the bearings inside the grease all thrown out What's the matter? Expert answer!
I think there may be three reasons1 may make you grease too much2 may be higher bearing temperature, more than the upper limit of the grease, the use of temperature caused oxidation deterioration of the oil, it is recommended to replace high temperature grease...3, you may use the brand of grease is not correct, change cone penetration of grease is betterIn addition, the consistency of grease and temperature are also related, in general, the higher the temperature, the thicker the grease
The quality of modern bearing bearingModern Behring (Tianjin) Machinery Equipment Co., Ltd. specializing in the sale of SKF bearings.

The way to do this is to do the same in everything we do.SKF's promise is the promise of the modern Behring, a promise that can be fulfilled.
Bearing heating causes:(1) the temperature of motor bearings is high. It is suspected that the gap between the couplings of the equipment is not adjusted properly, and a little vibration causes the excessive temperature rise of the bearings.(2) the rationality of the motor design, manufacturing quality, installation quality, etc..(3) bearing quality problems caused by heating, bearing gap.Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient (friction, coefficient) during movement, and guarantee its rotary accuracy (accuracy).According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts, namely, outer ring, inner ring, roller and cage. Strictly speaking, the rolling bearings are composed of six big parts, namely, outer ring, inner ring, rolling body, cage, seal and lubricating oil. Mainly with the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.
