50.02mm(1.969291"),49.94mm To 50.06mm, Large Solid Steel Balls For Big Bearing, G40
Product Details
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.
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.
Chrome balls are manufactured from the highest quality chrome alloy steel and through-hardened for maximum strength and service life. as the main part of bearing, are being widely used on the application like automotive industry, automobile, instruments, heavy machinery, engineering machinery and rolling mill machinery etc.
We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize our products to suit various needs of our customers.
