High Temperature Bearing

BMT is a bearing manufacturer established in 2004, producing High Temperature Bearings designed to operate in environments where conventional bearings fail due to lubricant breakdown or material deformation.

What Are High Temperature Bearings?

High Temperature Bearings are engineered to maintain stable mechanical performance under elevated temperature conditions where standard bearings are not suitable. In conventional bearings, lubricants typically degrade above 120°C, resulting in increased friction and wear.

BMT high temperature bearings are designed for operating ranges from 175°C up to 350°C for grease-lubricated types, and up to 1000°C for designs using ceramic materials and solid lubricants. The structure may include heat-resistant bearing steel, ceramic rolling elements, and high-temperature cage materials depending on application requirements.

These design configurations help maintain dimensional stability, reduce lubricant loss, and support continuous operation in thermal environments.

Typical Applications
Metal processing equipment, automotive heat zones, industrial ovens, drying systems, aerospace components, and power generation equipment.

Material & Design Options

Depending on operating conditions, high temperature bearings can be manufactured using:

Heat-resistant bearing steel for medium temperature environments
Ceramic rolling elements for extreme temperature resistance
Solid lubricants for lubrication stability at high temperatures
Special cage materials designed to reduce deformation under heat

Each configuration is selected based on load conditions, rotational speed, and temperature requirements.

Quality Control & Manufacturing

BMT conducts production under ISO 9001 and IATF 16949 quality management systems. Manufacturing processes include material inspection, heat treatment control, dimensional measurement, and performance testing to ensure consistency across production batches.

With more than 20 years of bearing manufacturing experience, BMT supplies bearing solutions for OEM manufacturers and industrial customers in Europe, North America, Southeast Asia, and the Middle East.

FAQ

What is the maximum temperature a high-temperature bearing can withstand?

The operating temperature depends on the material and lubrication system. Grease-lubricated high temperature bearings typically operate up to 350°C. For higher temperatures up to 1000°C, ceramic components and solid lubrication systems are required.

How does heat affect standard bearings?

High temperature can cause lubricant breakdown, oxidation, and evaporation, leading to increased friction and wear. It can also reduce steel hardness due to thermal effects and change internal clearances. High temperature bearings are designed to maintain structural stability under these conditions.
