KOYO bearing materials

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