Primarily, high carbon chromium bearing steel (Table 13.1) is used for the bearing rings and rolling elements. Most NSK bearings are made of SUJ2 among the JIS steel types listed in Table 13.1, while the larger bearings generally use SUJ3. The chemical composition of SUJ2 is approximately the same as AISI 52100 specified in the USA, DIN 100 Cr6 in
52100 / E51200 Bearing Steel, High Carbon-Chromium AMS
DescriptionApplicationsSpecificationsAvailable FormsHigh carbon, high chromium, aircraft quality bearing steel. This material develops high hardness, and exceptional resistance to wear and abrasion. In smaller sections it has a high compression strength. Furnished in the spheroidized annealed condition in order to provide the best possible machinability. 52100 Vac Melt E52100The effect of chromium in high carbon bearing steelsThe Effect of Chromium in High Carbon Bearing Steels J.M. BESWICK Chromium is present in the 52100 bearing steel composition in the range 1.30 to 1.60 wt pct. Chromium has a significant influence on the spheroidization of cementite, finer carbides being formed due to chromium additions.
The most common material used to produce the load carrying components in precision ball bearings, roller bearings, and tapered roller bearings is 52100 chrome steel. These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has high carbon and about 1.5% chromium content.
Bearing Steel Special Steel Bars and Tubes Products Unsurpassed high-cleanliness Bearing steel is special steel featuring 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.

Jul 01, 2019 · High-carbon chromium bearing steels with different rare earth (RE) contents were prepared to investigate the effects of RE on inclusions and impact toughness by different techniques. The results showed that RE addition could modify irregular Al 2 O 3 and MnS into regular RE inclusions. With the increase of RE content, the reaction sequence of
HIGH CARBON CHROMIUM BEARING STEEL, AND The high-carbon chromium bearing steel includes 0.5 wt % to 1.2 wt % of carbon (C), 0.15 wt % to 2.0 wt % of silicon (Si), 0.05 wt % to 0.45 wt % of manganese (Mn), 0.025 wt % or less (excluding 0 wt %) of phosphorus (P), 0.025 wt % or less (excluding 0 wt %) of sulfur (S), 0.1 wt % to 1.6 wt % of chromium (Cr), 0.01 wt % to 0.3 wt % of Ce, and iron (Fe) as well as other unavoidable impurities as a remainder.
Statistical duplex SN characteristics of high carbon Mar 01, 2010 · Statistical fatigue tests in the very high cycle regime were carried out for the high carbon chromium bearing steel (JIS:SUJ2) in rotating bending as a common research project. Duplex S N characteristics consisting of different S N curves for the surface-initiated fracture and the interior-initiated fracture were clearly confirmed.
Nov 01, 1987 · Chromium is present in the 52100 bearing steel composition in the range 1.30 to 1.60 wt pct. Chromium has a significant influence on the spheroidization of cementite, finer carbides being formed due to chromium additions. The ferrite to austenite transformation temperatures are increased due to chromium. The microchemistry of the cementite in 52100 changes during heat treatment; the chromium
