Introduction to high-temperature spherical outer surface bearings:

High-temperature spherical outer surface bearings are a special type of bearing, suitable for use in high-temperature and high-speed environments. They are usually composed of a spherical outer surface, an inner ring, a bearing housing, a sealing ring, and lubricating oil or grease. The design of this type of bearing enables it to maintain stable operation under extreme temperature conditions and is widely used in fields such as metallurgy, mining, petroleum, chemical engineering, and aviation.

The main characteristics of high-temperature insert ball bearings include:

Excellent high - temperature resistance: High - temperature outer spherical bearings can withstand high temperatures ranging from several hundred degrees Celsius to over a thousand degrees Celsius, ensuring the continuous operation of equipment under high - temperature working conditions.

The selection of materials is fastidious: It is usually made of high-temperature resistant alloy steel, ceramics, or other special materials. These materials are not only resistant to high temperatures but also have good corrosion resistance and wear resistance.

Structural optimization: Improve the heat dissipation efficiency and reduce the thermal expansion and thermal stress problems caused by high temperature by improving the internal structure of the bearing, such as adding heat dissipation channels and optimizing the raceway design.

Lubrication system innovation: Adopt solid lubricants, high - temperature greases or specially designed lubrication systems to ensure good lubrication performance even at high temperatures, reducing friction and wear.

Multiple types: High-temperature insert ball bearings are divided into multiple types such as high-temperature and high-speed, high-temperature and heavy-load low-speed, and ultra-high-temperature self-lubricating, which are suitable for different working conditions and temperature ranges.

The application scenarios of high-temperature spherical plain bearings mainly include the following types:

Metallurgical industry: In high-temperature, high-pressure, and heavy-load fields, spherical surface high-temperature resistant bearings are often used in steelmaking machinery, blast furnace machinery, continuous casting machinery, etc., to ensure the production efficiency and stability of the equipment.

Chemical industry: In corrosive media such as acids, alkalis, and salts, it is used in various chemical equipment such as pumps, valves, and agitators, and has excellent corrosion resistance.

Petroleum industry: In high-temperature, high-pressure, and corrosive environments, as the core component of oil pump equipment, it ensures the reliability and stability of the equipment.

Food industry: In high-temperature, high-speed, and high-hygiene-requirement environments, it is used in various food processing equipment to meet the hygiene requirements.

Pharmaceutical industry: In high-temperature and high-cleanliness-requirement scenarios, it is used in drug processing and production equipment, and has the characteristics of high speed, high load, high temperature resistance, and corrosion resistance.
