Rolling bearing has small friction

Rolling bearing has small friction resistance, can be preloaded, simple maintenance, lubrication, stable in a certain range of speed and load range. The rolling bearing is purchased by professional chemical factory for convenient maintenance. But compared with sliding bearing, the noise of rolling bearing is limited, and the stiffness change, vibration resistance and speed limit of rolling element are slightly poor. Machining center spindle in possible conditions, the use of rolling bearings, especially most of the vertical axis and spindle axial movement can be in the sleeve. When used in rolling bearings, grease can be used to avoid oil leakage. According to the structure of rolling element, rolling bearings are divided into ball bearings, roller bearings and tapered roller bearings. Self aligning roller bearing is selected here.
