Rolling bearing steel requiredments

Rolling bearing steel required steel dimensional accuracy is higher, this is because most bearing parts been formed though pressure. In order to save materials and improve labor productivity, most bearing rings are formed through forging, steel ball is formed though cold heading or molding, small size roller is is also formed though cold forging. If the dimensional accuracy of steel is not high, then it will not be able to calculate the sizes of materials and weight accurately, and can not guarantee the quality of bearing parts, and are likely to cause damage to equipment and tooling.
