There are many kinds of bearing materials. Stainless steel is probably the most common bearing material. Stainless steel bearings have certain advantages for ordinary bearings. As a one-stop service website for the bearing industry, China Bearing Network summarizes stainless steel according to understanding The following advantages of bearings.

Characteristics of stainless steel bearings:

AISI SUS440C stainless steel (domestic brand: 9Cr18Mo, 9Cr18) is used for bearing ring and rolling element material after vacuum quenching and tempering. The cage and sealing ring frame material is AISI304 stainless steel (domestic brand: 0Cr18Ni9).

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

Stainless steel deep groove ball bearings can resist corrosion caused by moisture and a number of other media. This type of single-row deep groove ball bearing is the same as the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel. It has a deep bearing raceway groove and a very high degree of fit between the bearing raceway and the ball.

Because of its high mechanical strength and large load capacity, stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery.

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 off without the need to re-lubricate to prevent the punishment of rust.

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

4. Slow depletion speed: AISI 316 stainless steel does not require oil or grease to protect against corrosion. Therefore, if the speed and load are low, there is no need for lubrication.

5. Sanitation: Stainless steel is naturally clean and does not corrode.

6. High heat resistance: Stainless steel bearings are equipped with high temperature polymer cages or cages without a complete complement structure, which can operate in a higher temperature range of 180°F to 1000°F. (Requires high temperature grease)
