There are many types of bearing materials. Stainless steel is probably the most common bearing material for everyone. Stainless steel bearings have certain advantages for ordinary bearings. As the bearing industry summarizes the advantages of stainless steel bearings based on their understanding.

Characteristics of stainless steel bearings:

The material of bearing rings and rolling elements is AISI SUS440C stainless steel (domestic grades: 9Cr18Mo, 9Cr18) after vacuum quenching and tempering. The cage and seal ring frame materials are AISI304 stainless steel (domestic grade: 0Cr18Ni9).

Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. Choose appropriate lubricants and dust caps, etc., and can be used in the environment of -60 ℃ ~ + 300 ℃.

Stainless steel deep groove ball bearings are resistant to moisture and corrosion caused by several other media. This type of single-row deep groove ball bearing has the same deep groove as the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel, and the degree of cooperation between the bearing raceway and the ball is extremely high.

Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery because of their high mechanical strength and large load capacity.

Advantages of stainless steel bearings:

1. Excellent corrosion resistance: Stainless steel bearings are not easy to rust and have strong corrosion resistance.

2. Washable: Stainless steel bearings can be washed down without having to relubricate to prevent the punishment of rust.

3. Can run in liquid: Due to the materials used, we can run bearings and bearing blocks in liquid.

4. Slow depletion speed: AISI 316 stainless steel does not require oil or grease anti-corrosion protection. Therefore, if speed and load are low, no lubrication is required.

5. Hygiene: Stainless steel is naturally clean and non-corrosive.

6. High heat resistance: Stainless steel bearings are equipped with high-temperature polymer cages or cages that are not in a complete supplementary structure, and can run at higher temperature ranges from 180 ° F to 1000 ° F. (Requires high temperature grease)
