Which synthetic greases are commonly used in German FAG bearings? FAG bearings have long been recognized as the reason why they are pioneers in rolling bearing technology. Today, FAG Bearings has become one of the leading brands in machinery manufacturing, automotive industry and aerospace technology. Bearing lubrication methods are roughly divided into grease lubrication and oil lubrication. In order to give full play to the function of the bearing, it is important to use the appropriate lubrication method according to the conditions of use and purpose of the bearing. Bearing grease is a lubricant composed of Base Oil, thickener and additive. When choosing, the grease that is very suitable for the conditions of bearing use should be selected.
