In the sphere of high-performance rotating equipment, Bearing Lubrication is far more than a simple lubricant; it is a critical engineering component. The primary goal is to establish a robust Elastohydrodynamic (EHD) lubrication film. This microscopic oil layer, often only a few microns thick, is responsible for separating the rolling elements from the raceways, neutralizing metal-to-metal contact and managing the distribution of load across the contact surfaces.
A typical grease consists of Base Oil (80–90%), Thickeners (such as lithium or polyurea), and Performance Additives. The thickener acts like a sponge holding the oil in a semi-solid matrix—this "glue-like" consistency keeps grease within the bearing while rolling motion "squeezes" the oil out for lubrication. By integrating these choices with Bearing Accuracy Standards, ZGBK ensures clearances are calibrated for thermal expansion.
