What are the advantages of stainless steel bearings?

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

Characteristics of stainless steel bearings:

The bearing ring and rolling element materials are made of AISI SUS440C stainless steel, which is vacuum-quenched and tempered, and the cage and seal frame materials are made of AISI304 stainless steel.

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

Stainless steel deep groove ball bearings can resist corrosion caused by moisture and several other media. This type of single row deep groove ball bearing is similar to the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel. It has a deep bearing raceway groove, and the fit between the bearing raceway and the ball is extremely high.

Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to 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 re-lubricate to prevent rusting.

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

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

5. Sanitation: 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 do not have a complete complement structure, and can operate at a higher temperature range of 180°F to 1000°F. (Need to be equipped with high temperature resistant grease)
