Steel Ball

Steel ball bearings are precision components widely used in mechanical equipment, mainly used to reduce friction and improve movement efficiency. Its basic structure consists of inner and outer rings, rolling elements (usually steel balls) and cages. Steel balls can effectively disperse the load and reduce friction resistance when rotating, thus improving the stability and life of the mechanical operation. Steel ball bearings have excellent wear resistance and load-bearing capacity and are suitable for high-speed operation environments. They are commonly used in automobiles, home appliances, aviation, industrial machinery and other fields. In addition, the manufacturing accuracy and surface treatment technology of steel balls directly affect the performance of the bearing, so strict control is required during the production process. With the advancement of science and technology, steel ball bearings are gradually developing towards high performance, low noise and long life to meet the higher requirements of modern industry for equipment reliability and efficiency.
