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 relubrication to prevent rust. 3. Can run in liquid: Due to the materials used, we can run the bearings and bearing seats in liquid. 4. Slow depletion rate: AISI 316 stainless steel does not require oil or grease for corrosion protection. Therefore, if 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 equipped with high-temperature polymer cages or without cages in a complete patchwork structure can operate at higher temperatures ranging from 180°F to 1000°F. (High temperature resistant grease is required) 2. The difference between stainless steel bearings made of 304 and 440. Stainless steel bearings are now divided into three materials: 440, 304 and 316. The first two are more common stainless steel bearings.The 440 material is definitely magnetic and can be attracted by magnets. 304 and 316 are micro-magnetic (many people say that it is not correct that they are not magnetic), that is, the magnet cannot attract it, but you can feel a little attraction. Generally, stainless steel bearing seats are made of 304 material. So which material of stainless steel bearing seat is better, 304 or 440? 304 is the most commonly used stainless steel. Compared with 440, the price is lower due to corrosion resistance and mechanical properties. Its comprehensive performance is more comprehensive, so it is more commonly used. But the disadvantage is that no further heat treatment can be performed to change its properties. 440 is a high-strength cutting tool steel (endnotes include A, B, C, F, etc.). It can obtain a higher yield strength after appropriate heat treatment and is among the hardest stainless steels. The most common application example is "razor blades".
