The choice of lubrication method for machine tool bearings is related to the bearing speed, load, allowable temperature rise, bearing type and related conditions. Next, Youwei will explain to you the precautions for grease lubrication of machine tool bearings.

Grease lubrication is characterized by strong lubricant adhesion, convenient use and simple maintenance, without the need for frequent addition and replacement of lubricants. But its frictional resistance is greater than that of oil lubrication. The most commonly used grease for machine tool bearings is lithium-based grease with mineral oil as the base oil, and compound barium-based grease with synthetic double-grease lubricant as the base oil can also be used for high-speed precision bearings. The rolling bearing should not be filled with grease too much, otherwise, the grease will melt and deteriorate due to stirring and heat and lose its lubricating effect. The grease filling amount of the bearing should be determined according to the type, size and working speed of the bearing.
