SUJ2 Special Steel Alloy for Bearing Purpose
SUJ2 hot rolled round bar is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings.
SUJ2 bearing steel is one kind of special steel with features of high wear resistance and rolling fatigue strength. High-carbon chromium bearing steel, engineering steel and some types of stainless steel and heat resistant steel are used as materials of bearings and for other purposes.
Advantages of SUJ2 Bearing Steel:
Superior hardness, 60-67 on Rockwell hardness scale (Rc) at room temperature
High carbon chrome alloy steel
Operates continually at temperatures up to 120°C
Used to produce precision ball bearings and roller bearings
Cost-effective
Long working life
SUJ2 special steel is mainly used for the manufacture of aircraft bearings and other highly stressed parts. This special steel is preferably vacuum arc re-melted to give optimum performance.
