Prospects for the Development of Stainless Steel Bearings

At present, the domestic form is to produce products without scale, and stainless steel bearings are a sunrise industry. Under the tide of internationalization, the stainless steel bearing market is facing strong challenges and opportunities, but it will also bring more opportunities for domestic stainless steel bearing manufacturers. The growth rate has always been very fast. Stainless steel bearings are a component of the special performance of the bearing industry. It also has better corrosion resistance because it not only has the mechanical properties of ordinary bearings. In special environments, it has a longer lifespan and better environmental performance. In today's increasingly environmentally friendly environment, stainless steel bearings are increasingly favored by people.
Due to the low technological content in China, as of now. People's awareness of environmental awareness is not high enough. Relevant information shows, however. Stainless steel bearings are still growing at an annual demand of 5-6%. Once the market starts, China will become a major bearing country. How big will this rich cake be? It goes without saying
Briefly introduce the performance, advantages, and disadvantages of several different types of stainless steel bearings, and take stainless steel bearings as an example. Provide more options for distributors preparing to test stainless steel bearings.
1、 440 stainless steel bearing: The ring and steel ball are both treated with AISISS440C9Cr18Mo or 9Cr18 through vacuum quenching and tempering. The 440 stainless steel bearing is used as a standard structure stainless steel bearing. Adhere to the use of AISI304 or AISI316 precision to ISO standard ABEC-5 vibration level Z3 group for the frame and sealing ring skeleton data. As a standardized stainless steel bearing, high-performance AISI440C stainless steel bearings provide high-precision and wear resistance comparable to chromium steel (bearing steel) on the basis of corrosion resistance. The most widely used type of stainless steel bearing currently has the advantages of low cost, high hardness, and being able to accept high loads and speeds. Advantages: The corrosion resistance effect is not very good. The disadvantage is that the rust resistance is not very strong.
II 316 stainless steel bearings: Compared to high carbon chromium martensitic stainless steel, 316 stainless steel bearings 440C stainless steel has better corrosion resistance and diamagnetism. Therefore, this bearing is not suitable for large loads and high speeds. Stainless steel cannot be hardened as a whole, but it has significant advantages in rust resistance and corrosion resistance. It is widely used in the chemical and electronic industries. The production process of pulp and paper has good corrosion resistance. 316 stainless steel bearings have better corrosion resistance than 304 stainless steel. Moreover, 316 stainless steel also has advantages in rust resistance and corrosion resistance Resistant to erosion by the ocean and corrosive industrial atmosphere.
3、 304 stainless steel bearing: 304 stainless steel bearing is a common type of stainless steel bearing. But the price is cheaper than 316 stainless steel. The corrosion resistance is superior to 440c stainless steel. The chemical grade of 304 stainless steel is 06Cr19Ni10 old grade. (0Cr18Ni9 contains 19% chromium and 8-10% nickel) has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. 304 stainless steel is an application
