Product Description

Product Description:

Automotive bearings are typically made from high-quality materials such as chrome steel, stainless steel, or ceramic. The bearings are designed with precision tolerances to ensure that they fit accurately and work efficiently. They also feature advanced lubrication systems that help to reduce friction and wear, which improves performance and extends the life of the bearing.

There are different types of automotive bearings available, including ball bearings, roller bearings, and needle bearings. Each type of bearing has its own specific design and features, which makes it suitable for different automotive applications.

Ball bearings are commonly used in automotive applications such as wheel bearings and gearbox bearings. They are designed to handle both radial and axial loads and are available in various sizes and configurations.

Roller bearings, such as tapered roller bearings and cylindrical roller bearings, are used in applications where high radial and axial loads are encountered, such as in the automotive transmission and differential systems.

Automotive bearings Advantage:

1.Improved performance: Automotive bearings are designed with precision tolerances and advanced lubrication systems that help to reduce friction and wear, which improves the overall performance of the vehicle. This results in better handling, smoother operation, and increased fuel efficiency.

2.Increased durability: Automotive bearings are designed to withstand the high speeds and loads that are typically encountered in automotive applications. They are made from high-quality materials that are resistant to wear and corrosion, which helps to extend their service life and reduce maintenance costs.

3.Enhanced safety: The proper functioning of automotive bearings is critical to the safe operation of a vehicle. Bearings that fail can cause serious accidents, so it is important to use high-quality bearings that are designed to meet strict safety standards.

4.Reduced noise and vibration: Automotive bearings are designed to reduce noise and vibration, which improves the overall driving experience. This can help to reduce driver fatigue and make the vehicle more comfortable to drive.

5.Wide range of applications: Automotive bearings are used in various parts of a vehicle, including the wheels, engine, transmission, and suspension systems. This makes them a critical component in modern vehicles, as they help to ensure safe and efficient operation.

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).
