Q:What are the specification size, weight and allowable deviation of size and weight of bearing steel round bar?

According to GB/T 18254-2016, the standard lists a variety of bearing steel grades, such as GCr15, GCr15SiMn, GCr15SiMo and so on. Different grades have different chemical composition and performance requirements. Secondly, the standard specifies the range of diameters of bearing steel rounds. The common diameter ranges include 5 mm to 250 mm, and the standard allows for certain deviations in the diameter of bearing steel rounds. The lengths of bearing steel rounds are not usually specified in the standards, but are determined according to the needs of the user and the capabilities of the manufacturer.
