DK28 diesel engine accessories introduce the general factors of poor bearing lubrication

1) Insufficient grease (grease)

2) The grease pipe is blocked by foreign matters, etc

3) The quality of lubricating grease (grease) is defective

4) Failure to add lubricating grease (grease) on time

5) The grease (grease) contains impurities

Bearing damage

As the main component, bearings are used for machines of various sizes. Some machines (such as crushers) have a lot of dust in the working atmosphere. When some fine dust enters the high-speed bearing seat, the bearing seat grease or grease will deteriorate, and the lubrication will be poor, resulting in bearing wear. Due to the increase of friction and heat, the bearing continues to operate, resulting in the bearing temperature rise.

Improper installation: another important reason for bearing heat. Because the bearing is installed correctly and its service life is directly related to the accuracy of the host machine, the centerline of the shaft and bearing hole must overlap

If the bearing is installed incorrectly, the accuracy is low, and the bearing has deflection, the torque will be generated during rotation, resulting in the bearing heating or damage. In addition, the bearing will also produce vibration and noise, which will increase the temperature

Inadequate cooling: generally manifested as: pipe blockage, improper use of cooling tower, poor cooling effect, etc.
