KOYO import bearing materials

Rolling bearing performance depends largely on the material performance. KOYO import bearings with low alloy and high purity usually overall quenching chrome steel imports and crafting KOYO bearing ring and rolling body material. To withstand the high impact load and alternating bending stress of KOYO import bearings, using carburizing steel. In recent years, due to KOYO import bearing steel quality continuous improvement ( Of course the price also rising) To make its KOYO import bearing capacity increases significantly. Research results and practical experience have proved that today's standard KOYO import bearings rolling bearing steel manufacturing, in good lubrication, clean environment and under the condition of load is not big, have infinite fatigue strength can be achieved. Rolling bearing ring and rolling body heat treatment process to ensure that KOYO import bearings within the 150 - degree, size stability. For higher working temperature, need to use special heat treatment method. If KOYO import bearings used in corrosive environment, you will need to KOYO import bearing steel are corrosive. Stainless steel standard KOYO import bearings in the code to add prefix 'S' and the suffix 'W203B'. The KOYO import bearings and the overall quenching KOYO import bearing steel KOYO import bearing the main size and carrying capacity is the same. In order to maintain its corrosion resistance, in the process of installation and use of the surface cannot be damaged. Production of silicon nitride balls used in ceramic bearing spindle K. Ceramic ball is much lighter than steel ball, centrifugal force and friction is significantly smaller than steel ball. When the KOYO import bearing grease lubrication in still can achieve high speed, and long service life, low working temperature.
