There are many kinds of bearing materials. Stainless steel may be the most common bearing material. Stainless steel bearings have certain advantages for ordinary bearings. According to the understanding, the following advantages of stainless steel bearings are summarized.
Characteristics of stainless steel bearings:
The bearing rings and rolling elements are made of AISI SUS440C stainless steel, which is vacuum quenched and tempered, and the cage and sealing ring skeleton 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, dust caps, etc., and can be used in the environment of -60°C~+300°C.
Stainless steel deep groove ball bearings are resistant to corrosion caused by moisture and several other media. These single row deep groove ball bearings, like standard deep groove ball bearings made of carbon-chromium steel, have deep bearing raceway grooves, 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 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 off without having to re-lubricate to prevent rusting.
3. Can run in liquid: Due to the material used, we can run the bearing and bearing seat in liquid.
4. Slower depletion: AISI 316 stainless steel does not require oil or grease for corrosion protection. Therefore, if the speed and load are low, lubrication is not necessary.
5. Hygiene: Stainless steel is naturally clean and does not corrode.
6. High heat resistance: Stainless steel bearings are fitted with high temperature polymer cages or without cages in a complete complementary structure and can operate at higher temperatures ranging from 180°F to 1000°F.
