Radial deep groove ball bearing lubrication:
Lubrication has an important impact on the fatigue life and friction, wear, temperature rise, vibration and so on of rolling bearings. Without normal lubrication, bearings cannot work.Analysis of the causes of bearing damage shows that about 40% of bearing damage is related to poor lubrication. Therefore, good lubrication of bearings is an effective measure to reduce bearing friction and wear. In addition, the lubrication of bearings has many functions, such as heat dissipation, rust prevention, sealing and impact mitigation.
Grease is a lubricant consisting of base oils, thickeners and additives. When choosing, we should choose grease which is very suitable for the use conditions of radial deep groove ball bearing. Because of different trademarks, there will be a great difference in performance, so attention must be paid to the selection.
The commonly used grease for radial deep groove ball bearing are calcium base grease, sodium base grease, calcium sodium base grease, lithium base grease, aluminum base grease and molybdenum disulfide grease.
The amount of filling grease in the radial deep groove ball bearing is appropriate to fill 1/2 to 1/3 of the internal space of the radial deep groove ball bearing. It should be reduced to 1/3 at high speed. Too much grease will increase the temperature rise.
Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces.
The viscosity of lubricating oil at bearing working temperature is generally 2-15cST.The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity.Commonly used lubricating oil are mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil and so on.
