How to choose imported bearing lubricating oil

Lubricant is an essential and necessary condition for bearings during operation, and is an important adjustment to reduce bearing wear and improve bearing life. The lubrication methods of imported bearings can be divided into grease lubrication and oil lubrication. Different imported bearings have different uses. The method and the lubrication method used are also different. Below, Demeirui Bearing shares the influence of the selection of imported bearing lubricating oil on the bearing.

Lubrication has an important influence on the fatigue life and friction, wear, temperature rise and vibration of imported eccentric bearings. Without normal lubrication, eccentric bearings cannot work. Analysis of the causes of damage to the vibrating eccentric bearing shows that about 40% of the damage to the vibrating bearing is related to poor lubrication.

The method of vibrating eccentric bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.

1. Eccentric bearing grease lubrication

Grease is a lubricant composed of base oil, thickener and additives. When choosing, you should choose a grease that is very suitable for the use conditions of eccentric bearings. Due to different varieties, there will be great differences in performance, so you must pay attention when choosing.

2. Eccentric bearing oil lubrication

Under the conditions of high speed and high temperature, oil lubrication can be used when grease lubrication is no longer suitable. Through the circulation of lubricating oil, a large amount of heat can be taken away, and it is also effective in reducing the vibration and noise of the eccentric bearing.

3. Grease viscosity of eccentric bearing

The viscosity of imported bearings is an important characteristic of lubricating oil. The size of the viscosity directly affects the fluidity of the lubricating oil and the thickness of the oil film formed between the friction surfaces. The viscosity of the lubricating oil at the working temperature of the vibrating eccentric bearing is generally 12--15cst. The higher the rotational speed, the lower the viscosity should be, and the heavier the load should be, the higher the viscosity should be. ·Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc.

In the process of storage and operation of imported bearings, reasonable use of lubricating oil can reduce the loss of bearings and enhance the service life of bearings.
