6300 Series Bearing
The lubrication method of 6300 Series Bearing is divided into grease lubrication and oil lubrication. In order to make the 6300 Series Bearing function well, 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 6300 Series Bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication. When lubricating, pay special attention to the dosage. Whether it is oil lubrication or grease lubrication, too little lubrication will affect the life of the 6300 Series Bearing, and too much will cause great resistance and affect the rotation speed.
