High Quality Gcr15 Bearing Steel Bar For Automobile
High Quality Gcr15 Bearing Steel Bar For Automobile
Feature
-
Bearing steel bar is used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness, wear resistance and high elastic limit. The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides of bearing steel are very strict, and it is one of the most stringent steel grades in all steel production.
1). Material: GCr15, 52100, SUJ1, SUJ2, 100Cr6, 1.2067, 55C, 8620, 4320, 9310, 440C, M50, as per customer’s requirement
2). Packing: standard sea-worthy packing
3). Surface treatment: punched, welded, painted or as per customer’s requirement
4). Size: according to customer’s requirement
Bearing steel bar can be divided into fully hardened bearing steel, carburized bearing steel, stainless bearing steel and high temperature bearing steel according to chemical composition, properties, processing technology and application.
1) High contact fatigue strength
2) High hardness or hardness that can meet the requirements of bearing performance after heat treatment
3) High wear resistance, low friction coefficient
4) High elastic limit
5) Good impact toughness and fracture toughness
6) Good dimensional stability
7) Good rust resistance and
8) Good cold and hot workability
Bearing steel bar is used to manufacture balls, rollers and sleeves of rolling bearings, and can also be used to manufacture precision measuring tools, cold dies, machine tool lead screws, such as dies, measuring tools, taps and precision coupling parts of diesel oil pumps. Bearing steel is used to make balls, rollers and bearing rings.
For example:
GCr15 bearing steel is widely used in the manufacture of engine bearings used in automobiles, tractors, tanks, aircraft, etc., spindle bearings used in machine tools, motors, etc., as well as bearings for railway vehicles, mining machinery, and general machinery.
GCr15SiMn bearing steel is mainly used to manufacture bearings with large wall thickness, such as various large and extra large bearings, and is mostly used in heavy machine tools and rolling mills without large impact loads.
