Introduction
GCr15 bearing steel ball, also known as chromium steel ball, is a kind of high carbon chromium bearing steel with low alloy content, good performance and the most widely used . After quenching and tempering, it has high hardness, good uniformity, good wear resistance and high contact fatigue property.
Steel has the characteristics of medium plasticity, low cutting performance, poor welding performance, high sensitivity to white spots, and high temper brittleness.
In addition, steel balls sizes of 30mm -82.55 mm are our company's main products used for large wind turbine bearings and slewing bearing.
Bearing balls are special highly spherical and smooth balls that are most commonly used in ball bearings, but are also used as components such as flywheel mechanisms. There are many different class of the ball. such as G3,G5,G10,G20,G28,G40,G60,G100 etc.
Our company's bearing steel balls are made of high-quality high-carbon chromium bearing steels GCr15 and GCr15SiMn. They are the best choice for various high-precision bearings.The best precision,make your bearing roll smoother.
