Stainless Steel Bearing

Stainless steel bearings are a type of rolling-element bearing that are made from stainless steel instead of traditional carbon or chrome steel. Stainless steel is a corrosion-resistant material that offers several advantages over traditional steel, including better resistance to rust and other forms of corrosion.

Product Description

Product Description:

Stainless steel bearings typically consist of an inner and outer ring, with steel balls positioned between them. The balls are held in place by a cage made of stainless steel or other materials, which maintains their relative positions and prevents them from coming into contact with each other.

Stainless steel bearings offer several advantages over traditional steel bearings, including better corrosion resistance, higher temperature capability, and better resistance to chemicals and other harsh environments. They are often used in applications where the bearings may be exposed to moisture, chemicals, or other corrosive substances.

Stainless steel bearings are available in a variety of sizes and designs to suit different applications, including deep groove ball bearings, angular contact ball bearings, and cylindrical roller bearings. They are often used in industries such as food and beverage, pharmaceuticals, and marine, where hygiene, cleanliness, and resistance to corrosion are important factors.

Stainless Steel Bearing Advantage:

1.Corrosion resistance: Stainless steel is a corrosion-resistant material that offers better resistance to rust and other forms of corrosion than traditional steel. This makes stainless steel bearings ideal for use in applications where they may be exposed to moisture, chemicals, or other corrosive substances.

2.Hygiene and cleanliness: Stainless steel bearings are often used in industries such as food and beverage, pharmaceuticals, and medical equipment, where hygiene and cleanliness are important factors. Stainless steel is easy to clean and maintain, and it does not corrode or react with cleaning agents.

3.High temperature capability: Stainless steel bearings can operate at higher temperatures than traditional steel bearings, making them suitable for use in high-temperature applications.

4.Resistance to chemicals: Stainless steel bearings are resistant to a wide range of chemicals and other harsh environments, which makes them suitable for use in applications where exposure to these substances is likely.

5.Low maintenance: Stainless steel bearings require less maintenance than traditional steel bearings, as they do not corrode or rust and do not require regular lubrication.

FAQ

What is the material of bearing steel?

Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel types in all steel production. In 1976, the International Organization for Standardization ISO incorporated some common bearing steel grades into international standards, and divided bearing steel into 17 categories: fully hardened bearing steel, surface hardened bearing steel, stainless bearing steel, and high temperature bearing steel. steel number. Bearing steel is mainly used to manufacture rolling elements and rings of rolling bearings. Since the bearing should have the characteristics of long life, high precision, low calorific value, fast speed, good rigidity, low noise, and high wear resistance, the bearing steel is required to have: high hardness, uniform hardness, high elastic limit, and high contact fatigue. Atmospheric lubricant strength, necessary toughness, certain hardenability and corrosion resistance. In order to meet the above performance requirements, the uniformity of the chemical composition of the bearing steel, the content and type of non-metallic inclusions, the particle size and distribution of carbides, and decarburization are strictly required. Bearing steel generally develops in the direction of high quality, high performance and diversification. Bearing steel is divided into high carbon chromium bearing steel, carburized bearing steel, high temperature resistant bearing steel, stainless steel bearing steel and special bearing material according to characteristics and application environment.

What is a bearing?

Bearings are parts that support the shaft, used to guide the rotational movement of the shaft, and bear the load transmitted from the shaft to the frame. Bearings are widely used and demanding supporting parts and basic parts in the machinery industry. They are the supporting components of the rotating shafts or movable parts of various machines, and are also the supporting components that rely on the rolling of rolling bodies to realize the rotation of the main engine. Known as mechanical joints.

What is the difference between high temperature resistant bearings and ordinary bearings?

Compared with ordinary bearings, high temperature bearings have high temperature resistance up to 500°C or 800°C, greater bearing capacity, oxidation and corrosion resistance, high hardness and wear resistance, strong impact and bite resistance, smooth and shiny appearance, self-lubricating, low There is no lubricant for those with high speed, the load is 1.4 times that of ordinary bearings, and the average life is more than five times that of ordinary bearings. In addition to being different in performance and material, the expression of the model is also different.

The parts of the bearing are made of bearing steel and subjected to high-temperature tempering treatment, and the post code is in accordance with the regulations of JB/T2974 (the parts have been subjected to high-temperature tempering treatment, and the working temperature can reach 150C°, and the code is /SO; the sh07 parts have been subjected to high temperature After tempering treatment, the working temperature can reach 200°C, and its code is /S1; after high-temperature tempering, the working temperature can reach 250°C, and its code is /S2; after high-temperature tempering, the working temperature It can reach 300°C, and its set code is /S3; after high temperature tempering treatment, the working temperature can reach 350°c, and its set code is /S4).

2. The parts of the bearing are made of heat-resistant steel, and its postcode is in accordance with the regulations of JB/T2974 (the material is Cr4Mo4V, and its postcode is /HN; the material is Cr14Mo4, and its postcode is HN1; the material is Cr15Mo4V, and its The postcode is /HN2; the material is W18Cr4V, and the postcode is /HN3).
