50.87mm(2.002756") Solid Chrome Steel Balls For Wind Turbine Bearing, G40
Introduction
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 higher hardness and uniform good performance structure.
Metal balls are spherical rolling elements that can 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.
The characteristics of the metal ball are the outer diameter, allowable deviation, surface roughness and tolerance. The outer diameter (OD) is the total width or average diameter of the ball. The allowable deviation is the maximum radial distance in the radial plane between the sphere around the surface of the metal ball and any point on the surface of the ball.
For example, Austenitic varieties have greater corrosion resistance and can be more easily formed thanks to the presence of concentrations of chromium and nickel. Ferritic steel balls are resistant to cracking and are extremely ductile, making them especially suitable for use in automotive settings.
Nitronic precision steel balls are often favored in the aerospace industry due to their resistance to galling, and Martensitic balls are heat treated to give them exceptional strength.
We also offer a range of grades of steel, such as AISI 52100 or 100Cr6. So pick the material and grade that meets your needs precisely.
The extremely precise and smooth surface of our chrome steel balls ensures that you will not find any defects such as flat surfaces, pits, soft spots, and cuts.
We mainly produce chrome steel, the size is 7.9375mm ~ 150.mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.
Properties and Advantage
[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 round.
[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 time] 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,rolling media, linear motion components and so on.
