Chrome Steel BearingsChrome steel is one of the most popular materials used in ball bearings, thanks to its excellent durability and cost effectiveness.Chrome vs. Stainless In addition to its affordability advantage, chrome steel bearings outperform stainless steel in some important application attributes. The superior hardness of chrome steels make them quieter in operation than comparable bearings of standard 440 grade stainless steel. Extra hardness also gives chrome steel bearings a longer working life, when properly maintained, than stainless alternatives.SAE 52100 The most commonly used chrome steel alloy in such applications is SAE 52100, a high carbon chrome alloy that can tolerate continuous temperatures as high as 120o C, with tolerances to 150o C on an intermittent basis. Bearings of 51200 require a protective oil coating on exterior surfaces to function effectively, making them unsuitable for environments which require a high degree of cleanliness or present the possibility of exposure to food products.Low corrosion resistance Despite its name, chrome steel actually has a low chromium content. This makes it prone to corrosion, rendering it less attractive than stainless steel or ceramic hybrid bearings in applications that require exposure to water or corrosive chemicals.
