不锈钢轴承生产厂家-上海御微轴承有限公司 表示防水轴承比一般轴承要牢靠防水、防尘、保油的效果。 Everyone knows stainless steel bearings, but I believe that many waterproof friends do n’t know the structure. In fact, there is a seal ring on the inner ring on one or both sides of stainless steel waterproof bearings. Here, the stainless steel bearing manufacturer-Shanghai Yuwei Bearing Co., Ltd. The company said that waterproof bearings are more reliable than ordinary bearings in the effects of water resistance, dust resistance and oil retention.
Features of stainless steel waterproof bearings:
Advantages 1. Excellent water resistance. It can be used under high temperature and stability, water vapor and steaming conditions, and water immersion;
Advantage two, outstanding oxidation resistance, useful to deal with common water dilution, hardening, emulsification and whitening, to ensure smooth underwater;
Advantages 3. All imported materials and additives can be used to wash with water and pressure in succession to achieve the ideal smooth effect and long service life.
The above is the introduction of the advantages of stainless steel waterproof bearings. In fact, stainless steel waterproof bearings have wet and slippery requirements for wet and waterproof papermaking machinery, smooth bearings, gears, and guide rails.
Stainless steel bearings have the characteristics of low vibration, low noise, and high rotation accuracy of ordinary bearings.They also have their unique performance characteristics: they can adapt to a wide range of environments, and are resistant to acids and alkalis and corrosion.They can be used in seawater, river water, distilled water, dilute nitric acid, marine steam.
However, everyone must know why stainless steel is not easy to rust. It is related to the addition of more than 12.5% chromium in the matrix. In oxidative corruption incapable corrosion media, chromium can quickly form a dense passivation film on the surface of the steel to prevent The metal substrate is damaged. When the chromium content is above 12.5%, a dense and stable passivation film is formed. The rust prevention performance is progressively changed, and the rust resistance is greatly enhanced. This is why the stainless steel contains chromium. There must be more than 12% of the amount.
The chromium content in stainless steel is about 13% -18%, and the nickel content is about 8% -11%. These two metal elements have high corrosion resistance in corrosive media, so stainless steel generally does not undergo oxidation reactions (rust ).
The rust is essentially corrosion or called rust, which is caused by chemical or electrochemical interaction between the surface of steel and the oxygen, moisture and acids, alkalis, salts and other substances in the atmosphere. The resulting substance is an oxide of rust or iron.
Stainless steel, as its name suggests, is stainless steel, where "stainless" is relative, not absolute, relative to carbon steel. Stainless steel is not easy to rust, but it is not absolutely rusty, but it is less likely to be corroded and rusted than carbon steel in the same conditions and environment.
