Deep groove ball bearings are widely used rolling bearings, which are characterized by low friction resistance, high speed, and the ability to withstand radial loads or combined loads acting radially and axially at the same time. The materials of deep groove ball bearings include but are not limited to carbon steel, bearing steel, stainless steel, plastic, ceramic, etc. Among them, the bearing rings and steel balls are usually made of GCR15 (AISI 52100) refined bearing steel, and the retainer is stamped from 08F high-quality cold-rolled steel strip.
The materials of deep groove ball bearings also include high carbon chromium steel, which is a heat-treated material with excellent strength and wear resistance, suitable for high load and high speed conditions. Stainless steel materials have excellent corrosion resistance and are often used in humid or chemically corrosive environments. Ceramic materials such as alumina ceramics and silicon nitride ceramics have the characteristics of high strength, high hardness, low friction coefficient, etc., and are suitable for high-speed, high-temperature, and high-precision application scenarios.
In addition, there are miniature deep groove ball bearings, which are also made of various materials, including carbon steel, stainless steel, plastic, ceramic, etc., among which various types of bearings with an outer diameter of less than 9.525mm in the imperial series are also widely used.
On the assembly drawing, the material of the deep groove ball bearing is usually clearly marked, including but not limited to material type, hardness grade, precision grade, etc., to ensure its suitability and performance in specific applications.
