Chrome Steel 52100 is a universal material for many applications. Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and a consistent high quality.
ATS has the most comprehensive chrome steel ball production lines. We use high quality vacuum degassed steel and adopt world-class technology. With its high quality on surface, high hardness and heavy load, our high precision products have met the requirements of world-famous customers. The balls have been applied into precision Motor bearings, precision machinery, rolling screws, and so on.
Universal material for ball and roller bearing industry. Chrome steel balls contain chromium and due to through hardening has an excellent surface quality and high load bearing.
Excellent hardness control with a through hardness of HRC 60 to 67.
Universal for many applications. For example: balls & roller bearings. Linear monition, balls lead screws, grinding media.
0.98 to 1.10%
Packaging & Shipping
The package is carton box and wooden pallets. All the shipping ways is available, by sea or air.
Ball Production Process
Raw material, wire drawing:The wire rod is drawn to the required size, in closer tolerance so that it can be used in cold forging.
Cold forging:Calculated length of wire is sheared and cold forged in a close die to give it the spherical shape.
Flashing: The rolling between plates with concentric grooves in order to eliminate the heading witness marks and in increase the precision of the ball, in this operation the spheres are ground between two concentric pressure plates to correct the spherical shape and remove the seam formed in the cold forging.
Heat treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
Descaling: This step removes the residues and by-products on the preceding process.
Hard Grinding: Here the hardened balls are ground to improve surface finish and geometrical parameters. Several careful grinding processes with ceramic wheels lead to a higher size precision preparing the balls for the next final lapping operation.
Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, increasing wear resistance and product longevity.
Inspecting: All products pass through proprietary, automated inspection process.
