Product Details
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. Metal balls are characterized by the Outer Diameter, Permissible Deviation, Surface Roughness and Tolerance. The Outer Diameter (OD) is the overall width or average diameter of the ball. Permissible Deviation is the greatest radial distance in a radial plane between a sphere around the metal ball surface and any point on the ball surface.
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. This kind of steel has general cold working plasticity, poor welding performance, high sensitivity to the formation of white spots, and temper brittleness.
The chromium balls are made of the highest quality chromium alloy steel and are quenched to achieve maximum strength and service life. As the main part of the bearing, it is widely used in the automotive industry, automobiles, instrumentation, heavy machinery, engineering machinery and rolling mill machinery and other fields.
We are a supplier of balls for the wind turbine market. The most common steel ball use in the energy sector is in the crucial pitch and yaw bearings that give wind turbines their motion.
We are a major supplier to the oil production industry. We supply S-2 rockbit tool steel balls for down-hole drilling and for use in mud motors.
We are a key supplier of 52100 chrome, carbon, and stainless steel precision, and non-precision balls for applications involving industrial, automotive and commercial motion devices, such as race bearings, sliding doors, furniture, water pumps, cut off-valves, and even appliances.
Although these chrome steel balls have good rust resistance, it is recommended to wipe them with a dry cloth and apply a layer of oil after use to make them have better rust resistance and extend their service life.
We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize products to meet the various needs of customers.
Complete quality and material certifications by lot number are available for all products we sell. We proudly offer:
· Modern process engineering
· A commitment to excellence amongst our staff and manufacturers
· Constant control throughout every stage of production, from the manufacturing side to sales and operations.
