1. Introduction
The cold drawn bright seamless stator tube is a cold drawn seamless steel tube used to make ordinary rolling bearing rings.Cold drawn bright seamless stator tubes are subject to high pressure and friction, so the bearing steel used has high and uniform hardness and wear resistance, as well as high elastic limit.
