Reasons for high temperature of precision bearings in operation

Cross Roller Bearings

The bearing temperature in the machine is too high, which is a common and harmful fault of rotating equipment.

Improper handling will reduce the service life of the bearing, increase the maintenance cost, and even cause the bearing to burn out, thereby causing devastating damage to the machine!

1. Poor lubrication

Lubrication has an important influence on the service life of the bearing, friction, wear, vibration, etc. Good lubrication is a necessary condition to ensure the normal operation of the bearing. According to statistics, about 40% of bearing damage is related to poor lubrication. The factors that usually cause poor bearing lubrication are: Insufficient lubricating oil (grease) The lubricating oil pipe is blocked by foreign matter, etc. There is a problem with the quality of the lubricating oil (grease) Not adding lubricating oil (grease) on time Lubricating oil (grease) contains impurities

2 .Bearing wear Bearings.

As important parts, are used in various large and small machines, and some machines work in the open air, and when there is a lot of dust, part of the fine dust is easy to enter the high-speed running bearing seat, causing the lubricating oil or grease in the bearing seat to deteriorate. Poor operation, and then the bearing wear. Bearings continue to run in a worn state, and heat increases due to increased friction, resulting in increased bearing temperatures.

3 . Improper installation

Improper installation is another important cause of bearing heating. Because the bearing is installed correctly or not, it has a direct impact on its life and the accuracy of the host, so the centerline of the shaft and the bearing hole must be coincident during installation. If the bearing is installed incorrectly, the accuracy is low, and the bearing has deflection, torque will be generated during rotation, causing the bearing to heat up or wear. In addition, the bearing will generate vibration, increase the noise, and increase the temperature rise.
