Usage and Applications of Bearing Steel Round Bar
Bearing steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.
First the famous 1C-1.5Cr steel from which the majority of bearings are made. Its structure is apparently well-understood and the focus is on purity in order to avoid inclusions which initiate fatigue during rolling contact. Then there is the M50 steel and its variants, from which bearings which serve at slightly higher temperatures in aeroengines are manufactured, based on secondary-hardened martensite.
Tapered roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling ,During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

FAQ：
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q2: What makes stainless steel stainless?
A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
