Lubrication

Grease lubrication or oil lubrication. The seat ring is provided with a lubrication groove and a lubrication hole is opened in the middle. The lubricant is introduced between the two rows of rolling elements, and the purpose of lubrication is achieved by the function of the bearing running and conveying. It is this high delivery effect that requires a much larger lubrication dose than the adjacent cylindrical roller bearings. Therefore, the design needs to ensure that the oil flowing from the thrust angular contact ball bearing cannot enter the adjacent cylindrical roller bearing.
