First, the 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 punishment.

3, can run on the liquid: due to the materials used, we can run the bearings and housings in the liquid.

4, the depletion speed is slow: AISI 316 stainless steel, no oil or grease anti-corrosion protection. Therefore, if the speed and load are low, there is no need to lubricate.

5. Hygiene: 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 are not in a complete complementary structure and can operate at higher temperatures ranging from 180°F to 1000°F. (Need to be equipped with high temperature grease)

Second, 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 relatively common stainless steel bearings. The 440 material is definitely magnetic, that is, the magnet can be sucked. 304 and 316 are micro-magnetic (many people say that he is not magnetic, this is not true) that is, the magnet can not absorb, but you can feel a little suction. Generally stainless steel housings are made of 304 material. So is the material of the stainless steel housing 304 good or 440? 304 is the most used stainless steel, the price is lower than the 440 anti-corrosion ability, mechanical properties, etc., the comprehensive performance is more comprehensive, so it is more common applications. The disadvantage, however, is that no further heat treatment can be performed to change its performance. 440 is a high-strength cutting tool steel (tailed with A, B, C, F, etc.), which can obtain a high yield strength after proper heat treatment, and is among the hardest stainless steel. The most common application example is the “razor blade.”
