Koyo adopts high-quality materials in the manufacturing of their bearings to ensure exceptional performance and durability. The Koyo bearing material used vary depending on the specific application and operating conditions, but all are carefully selected and rigorously tested to meet stringent quality standards. For example, Koyo uses premium-grade steel to manufacture the bearing rings, which are then heat-treated and precision-ground to exact tolerances. The rolling elements are also made from selected materials to ensure reliable operation and long service life. Koyo bearing materials undergo strict quality control measures to ensure consistency and reliability, resulting in bearings that are capable of withstanding demanding conditions and providing reliable performance. Koyo’s commitment to using high-quality materials is reflected in their reputation for producing some of the most reliable and long-lasting bearings in the industry.
SKF imported bearings (especially rolling bearings) are of two structures with cage and without cage. Among them, large SKF imported bearings are generally required to bear a large load, often without cage, but filled with rolling elements between the inner and outer raceways. Most small and medium-sized rolling bearings have cages.Performance of Koyo bearing material after heat treatment
