52100 Bearing Steel

52100 steel is a deep hardening alloy used for aircraft bearings or other high stressed parts where good rolling contact fatigue strength is required at temps below 400 degrees. The 52100 vac melt steel material offers superior cleanliness and internal soundness over the conventional air melted SAE 52100.

52100 is a through hardening bearing steels intended for rolling contact and other high fatigue applications. In the hardened condition the high hardness, high strength and high cleanliness provides the steel with the right properties to withstand high cycle, high stress fatigue. 52100 is mainly used for small and medium sized bearing components. It is also regularly used for other machine components that require high tensile strength and high hardness.

52100 Round Bars 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 Chrome Bearing Steel 52100:

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

 

Applications of 52100 Bearing Steel

Alloy steel 52100 grade bearing steel is mainly used for the manufacture of aircraft bearings and other highly stressed parts. This steel grade 52100 steel is preferably vacuum arc re-melted to give optimum performance. Typical applications: Bearing Manufacture, CV joints, ball screws, gauges, knife etc
