Advantages of stainless steel bearings and the difference between stainless steel shaft 304 and 440 materials
1.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 cleaned without cleaning to avoid rust.
3.Can run in liquid: Due to the materials used, we can run bearings and housings in liquid.
4.Depletion is slow:AISI 316Stainless steel does not require oil or grease for corrosion protection. Therefore, if the speed and load are low, no lubrication is required.
5.Hygiene: stainless steel is naturally clean and will not corrode.
6.High heat resistance: Stainless steel bearings are equipped with high-temperature polymer cages or cages without complete complementary structures.180°FTo1000°Foperation within the higher temperature range.
2,Stainless Steel Bearings304with440The material difference
Now, stainless steel bearings are divided into three materials:440,304and316. The first two are the more common stainless steel bearings.440The material is absolutely magnetic, which means that magnets can be absorbed.304and316It belongs to micromagnetism (many people say that it is incorrect that he does not have magnetism), that is, the magnet cannot absorb, but you will feel some suction. Usually, the stainless steel housing is made304Made of material. Well, the stainless steel housing is made304Still440Made?
304Is a commonly used stainless steel. with440In terms of corrosion resistance and mechanical properties, the price will be lower. Comprehensive performance is more comprehensive, so it is more commonly used. But the disadvantage is that it cannot be further heat treated to change its properties.
440High strength cutting tool steel. After proper heat treatment, higher yield strength can be obtained, which belongs to hard stainless steel. Common application examples are“Shaver”.
