Advantages of stainless steel bearing seats

1、 Advantages of stainless steel bearing seats

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 for re lubricating oil to prevent rusting as a punishment.

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

4. Slow depletion rate: AISI 316 stainless steel does not require oil or grease 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 equipped with high-temperature polymer cages or cages without a complete compensation structure, and can operate in a higher temperature range of 180 ° C; F to 1000° F. (High temperature resistant grease required)

2、 The difference between stainless steel bearings 304 and 440 materials

Stainless steel bearings are now divided into three materials: 440, 304, and 316. The first two are common types of stainless steel bearings. The 440 material is definitely magnetic, which is what magnetite can absorb. 304 and 316 belong to micro magnetism (many people say it's not true that they don't have magnetism), which means that the magnet can't hold on, but you can feel a little bit of attraction. Generally, stainless steel bearing seats are made of 304 material. So is the material of stainless steel bearing seat 304 or 440 better?

304 is a commonly used stainless steel, which has lower corrosion resistance and mechanical properties compared to 440. Its comprehensive performance is comprehensive, making it widely used. But the disadvantage is that further heat treatment cannot be carried out to change its performance.

440 is a high-strength cutting tool steel (with notes A, B, C, F, etc. at the end) that can achieve high yield strength after appropriate heat treatment, and belongs to the category of hard stainless steel. A common application example is the razor blade.
