50.74mm(1.997638") High precision bearing Balls For Bearing, G40
Introduction of steel ball
GCr15 steel has low alloy content and good performance. It is currently the most widely used bearing steel. After quenching and low temperature tempering, it will have relatively high hardness and uniform structure of good performance. This kind of steel the cold working plasticity is general, the welding performance is poor, the sensitivity to the formation of white spots is large, and it has temper brittleness.
Metal balls are spherical rolling elements that provide rotary or linear motion for ball valves, check valves, bearings and other mechanical equipment. They are usually made of alloy steel, carbon steel or stainless steel. It is characterized by the outer diameter, tolerance, surface roughness and tolerance of the metal ball. The outer diameter (OD) is the total width or average diameter of the ball.
High requirements for smelting quality of bearing steel, and the content and distribution of sulfur, phosphorus and non-metallic inclusions need to be strictly controlled, because the content and distribution of non-metallic inclusions have a great impact on the life of bearing steel. The basic quality requirements for bearing steel are purity and uniform organization. Purity means that there are fewer impurity elements and non-metallic impurities, and the uniform structure means that the carbides in the steel should be fine and evenly distributed. The higher the amount of inclusions, the shorter of the life span. In order to improve the quality of smelting, electric furnace smelting and electroslag remelting have been used recently, and new processes such as vacuum smelting and vacuum consumable refining can also be used to improve the quality of bearing steel.
The chromium ball is made of the highest quality chromium alloy steel and is quenched to achieve maximum strength and service life. Ideal applications for chrome balls include rolling media, spray tank mixing, ball bearings, wind turbine bearings, and linear motion components. The most widely used in various industries.
Our chrome Steel Balls extremely precise and smooth surface guarantees you won't find any defects, such as flats, pits, soft spots, and cuts.
We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.Our balls are mainly for wind energy industry.
Properties
[High-quality material] Made of high-quality chromium steel, high-grade bearing steel, corrosion resistance, high precision and high hardness. Polished surface, smooth without burrs, standard shape and high precision, completely circular.
[Anti-rust] Corrosion resistance and high oxidation resistance. It is also suitable for humid environments. The surface is coated with a small amount of grease to improve lubrication and prevent corrosion and rust.
[Long use] The heat treatment process can make the bearing ball stronger and bear high pressure and wear resistance.
[Wide application] Widely used in wind turbine bearings, yaw bearing, slewingring bearing and so on.
