Hot Sale GB Standard GCr9 / GCr9SiMn / GCr15 / GCr15SiMn Bearing Steel Round bar

Short Description:

Rolling bearing steel is steel used to manufacture rolling elements and inner and outer rings of rolling bearings, and is usually used in a quenched state. Commonly used rolling bearing steels are high-carbon, low-chromium bearing steels with a carbon content of 0.95% to 1.10% and a chromium content of 0.40% to 1.60%, such as GCr6, GCr9, GCr15, etc.

    steel bar

    GCr9, GCr9SiMn, GCr15, and GCr15SiMn are all types of bearing steel grades commonly used in the production of bearing components. Here are the typical details of bearing steel round bars for these grades:

    Material: GCr9, GCr9SiMn, GCr15, and GCr15SiMn bearing steel round bars are typically made from high-carbon chromium steel, with GCr15 being the most widely used grade. These steels contain varying amounts of carbon, chromium, and other alloying elements to provide high hardness, wear resistance, and fatigue strength.

    Diameter: The diameter of bearing steel round bars can vary widely based on the specific application requirements, ranging from a few millimeters to several inches.

    Surface Finish: The bars are typically supplied with a smooth, polished surface finish to ensure precision and reduce friction in bearing applications.

    Hardness: Bearing steel round bars are heat-treated to achieve high hardness, typically in the range of 60-65 HRC (Rockwell hardness scale) to provide excellent wear resistance and load-bearing capacity.

    Tolerance: Precision tolerances are maintained to ensure uniform diameter and straightness along the entire length of the round bars, meeting industry standards and customer specifications.

    Applications: Bearing steel round bars are primarily used in the production of various types of bearings, including ball bearings, roller bearings, and thrust bearings, as well as in other high-precision mechanical components where high hardness, wear resistance, and load-carrying capacity are essential.

    If you need more detailed information, it is recommended to consult us for detailed information on the specific specifications and uses of these alloy steel bars.
