In mechanical design, the "ultimate speed" of bearings is a often overlooked but crucial parameter. It refers to the maximum rotational speed at which a bearing can operate safely and stably under specific lubrication and installation conditions. Once the actual working speed exceeds this threshold

1、 What is the basic size?Basic dimensions refer to the theoretical dimensions marked on the design drawings of the parts, which can also be understood as the dimensions in the "ideal state". For example, if the inner diameter of a bearing is marked as 50mm, this 50mm is its basic size.It is the
