Development Prospects 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.

It has been growing rapidly. Stainless steel bearing is a component of a special performance in the bearing industry. It also has better corrosion resistance, because it not only has the mechanical properties of ordinary bearings. In the special environment, it has longer service life and better environmental protection performance. Nowadays, people pay more attention to environmental protection, and stainless steel bearings are more and more favored by people.

As the domestic scientific and technological content is not high, at present. People's awareness of environmental protection is not high enough.  

Relevant information shows, however. The demand for stainless steel bearings is still growing at 5-6% per year.  

Once the market starts, China is a big-bearing country. How big will this rich cake be? It goes without saying

This paper briefly introduces the service performance, advantages, and disadvantages of several different types of stainless steel bearings. The following is an example of stainless steel bearings. Provide more options for dealers who are preparing to test the water of stainless steel bearings. 

1、 440 stainless steel bearing

The ferrule and steel ball is made of aisisus440c9cr18mo or 9Cr18 after vacuum quenching and tempering. 440 stainless steel bearing is used as stainless steel bearing with standard structure. AISI304 or AISI316 shall be adopted for the framework data of the holder and sealing ring, and the accuracy shall reach the vibration level Z3 group of ISO specification ABEC-5.  

As a stainless steel bearing with a standard structure, high-performance aisi440c stainless steel bearing also provides high precision and wear resistance comparable to chromium steel (bearing steel) on the basis of corrosion resistance. At present, it is the most widely used stainless steel bearing The utility model has the advantages of low price, high hardness, and can accept the high load and high speed.  

Advantages: the corrosion resistance effect is not very good. The disadvantage is that the anti-rust ability is not very strong.  

2、 316 stainless steel bearing

Compared with high carbon chromium martensitic stainless steel (440C stainless steel), 316 stainless steel bearing has better corrosion resistance and magnetic resistance. Therefore, the bearing is not suitable for large loads and high speeds. Because stainless steel cannot be hardened as a whole, it has great advantages in rust resistance and corrosion resistance. It is widely used in chemical and electronic industries. It has good corrosion resistance in the production of pulp and paper.

The corrosion resistance of 316 stainless steel bearing is better than that of 304 stainless steel. Moreover, 316 stainless steel is also resistant to marine and aggressive industrial atmospheres.  

3、 304 stainless steel bearing

304 stainless steel bearing is a common stainless steel bearing. But the price is cheaper than 316 stainless steel. The corrosion resistance is better than 440C stainless steel.  

The chemical grade of 304 stainless steel is the old grade of 06cr19ni10. (0Cr18Ni9 contains 19% chromium and 8-10% nickel) with good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. 304 stainless steel is the most widely used chromium-nickel stainless steel.  

If the area is heavily polluted by industrial gas, it is corrosion-resistant in the atmosphere. It needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage, and transportation. It has good machinability and weldability. Plate heat exchanger, bellows, household products, building materials, chemical, food industry, etc.  

304 stainless steel is a nationally recognized food-grade stainless steel. Corrosion resistance and non-magnetic, stainless steel bearings have good oxidation resistance. It is especially suitable for the harsh production environment, with large acceptance capacity; High service life; Maintenance-free, realizing high strength, and high precision. Because of its high mechanical strength and large load capacity. Stainless steel bearings can be used under special conditions such as acid and water resistance. Medical machinery is widely used in food processing. In terms of pharmaceutical machinery, it is widely used.  

With the development of stainless steel bearings, they are suitable for most industries. Domestic stainless steel bearing plants have ushered in spring.
