What is the self-centering function?

What is the self-centering function?

The self-centering function refers to the function to suppress the runout of the hub when the shaft and hub are tightened.

In other words, it is a function of how much the axis can be brought to the center of the hub.

POWER-LOCK has a series with or without a self-centering function. For a series without a self-centering function, the hub must be provided with a guide part (a part where the shaft and hub come into direct contact).
