1. Overheating Overheating of the microstructure after quenching can be observed from the rough mouth of the SFC bearing parts. But to accurately determine the degree of overheating, it is necessary to observe the microstructure. If coarse needle like martensite appears in the quenched structure of GCr15 steel, it is a quenched overheated structure.

Annealing, also known as simmering, code name Th, is the process of heating a steel piece to Ac1 or Ac3 or above (30-50 ℃), holding it for a period of time, and then slowly cooling it (usually using furnace cooling).Normalization, also known as open flame, code Z, is the process of heating steel parts to Ac3 or Acm or above (30-50 ℃), holding them for a period of time, and then cooling them in air at a slightly faster cooling rate than annealing.The main difference between bearing annealing and normalizing is that normalizing is a deformation or special case of complete annealing, and the only

In the wave of global industrial development, bearings, as key basic components, silently support the efficient operation of various mechanical equipment and are essential "joints" in the industrial sector. In order to meet the diversified needs of customers, assist enterprises in going global, and achieve zero distance across regions, the Chinese manufacturing platform has planned a live streaming event called "Super Going Global Season". We are honored to participate in this upcoming event and will be waiting for you in the live broadcast room.

What material is bearing steelBearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearing steel has high and uniform hardness, wear resistance, and high elastic limit. Strict requirements are placed on the uniformity of chemical composition, content and distribution of non-metallic inclusions, and distribution of carbides in bearing steel, making it one of the most stringent steel grades in all steel production.

1. High end and precisionWith the rapid development of manufacturing industry and the promotion of industrial upgrading, the market demand for high-end bearings will continue to increase. Enterprises need to increase investment in technological innovation and research and development, improve product quality and performance levels, in order to meet the market's demand for high-performance and high-quality bearing products.Precision manufacturing is one of the development directions of the bearing manufacturing industry.

The so-called burn damage state of  bearings refers to the rapid heating of the raceway wheel, rolling element, and retainer of  bearings during rotation until discoloration, softening, deposition, and damage occur.The main reason for bearing burns is due to poor lubrication of  bearings, which may have used non-standard lubricants or excessive or insufficient lubricants, both of which are incorrect. Secondly, it may be due to excessive load (excessive preloading). The rotational speed is too high. The clearance is too small. There is water or other foreign objects invading.

In recent years, ceramic bearings have been increasingly used in various fields, such as aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, and national defense and military. The advantages of using ceramic bearings in new products are becoming increasingly apparent. The following is a specific understanding of the advantages of using ceramic bearing materials.The advantages of ceramic bearing materials mainly include the following:1.

Bearings are a very important part of machinery and equipment. They perform the key functions of supporting and transmitting loads, reducing friction and energy loss, and ensuring stable machine operation. The following are a few aspects of the importance of bearings:1. Supporting and transmitting loads: A bearing transmits loads to other parts of the machine by withstanding forces from the machine's motion and external loads. It supports and distributes the load, ensuring that the machine remains stable when running at high speeds or under heavy loads.2.
