Seizing between shofts and bearings is an incidental occurence, so it is difficult to make clear the phenomenon, but it is well-known that its mechanism consists of two processes, birth of the seizing-mucleus and its growth. Therefore, there is no seizure where theie is no seizing-nucleus to come out and even if it does come out it does'nt motter if there is no growth of nucleus.
To make clear the property of seizing, we must study the way of rise of seizing-nucleus and the process of growth of the nucleus. It is the object of the 1st report to make research on how grows the sezing-nucleus on bearing metals.
First, to find out the growing mark of a sezing-nucleus on bearing metals from replica caused by roughness of shaft surface on it, the order of replica by shaft's roughness is innestigated. Then it is found that replica is affected not by load but by its roughness, and that the roughness replicated is less than about Hmax=0.5μ.
From the results exprimented on seizing up, it was made clear that there are three typical growing of the nucleus, Slender, Flat and Similer and that among which Slender type is the most suitable one for bearing metals.
