The so-called high-temperature bearings refer to those whose operating temperature is higher than that of ordinary bearings. Generally, bearings used with operating temperatures above 150° are called high-temperature bearings.
Your Leading Extreme Temperature Deep Groove Ball Bearing Supplier

Features of Extreme Temperature Deep Groove Ball Bearing
No need for relubrication
All variants, except open bearings (without shields) with a stamped steel cage (VA201 design), are lubricated for the life of the bearing with graphite-based high temperature lubricants. Open VA201 bearings may require relubrication .
Simple replacement
The boundary dimensions are the same as those of standard bearings.
Operating temperature up to 350 °C (660 °F)
The internal radial clearance and the lubricant are optimized for operation at high temperatures.
Protection against solid contamination
Shields (designation suffix 2Z) protect the bearing.
Improved running in
The entire bearing surface is manganese phosphate coated.
Specifications of Extreme Temperature Deep Groove Ball Bearing
Common Materials of Extreme Temperature Deep Groove Ball Bearing
High-Temperature Steel Alloys
While lubrication plays a key role in high temperature bearing performance, material selection fundamentally defines heat resistance
High temperature steel alloys are mainly used for the balls and raceways of rolling bearings.
Ceramic
Ceramic is often used for high temperature bearing parts like balls, rollers, and rings.
It resists heat, doesn't expand much with temperature changes, and wears down slowly.
This makes it a good choice for hot areas where it's hard to use lubrication.
Graphite-Metal Alloy
Graphite-metal alloys are mainly used in sliding bearings and cages.
They work well in high-heat areas where self-lubrication is needed to keep things running smoothly without extra grease or oil.
High-Temperature Polymer and Composite Materials
High-temperature polymer and composite materials are mainly used for cages, sliding components, and other non-rolling parts.
It resists high heat and chemical corrosion, and has a low friction coefficient.
This makes it ideal for high-temperature applications where smooth, low-friction movement is needed.
Usage Precautions of Extreme Temperature Deep Groove Ball Bearing
Material degradation: High temperatures can accelerate material fatigue, causing the performance of bearing materials such as metals or plastics to degrade.
Lubrication failure: High temperatures can easily cause the thermal decomposition of traditional lubricating oils and greases, losing their lubrication effect, thereby increasing wear and friction.
Thermal expansion: Materials will expand in a thermal environment, which may cause changes in the internal clearance of the bearing and affect the precise operation of the bearing. Different materials have different coefficients of thermal expansion, which can lead to mismatches between the internal components of the bearing.
Corrosion acceleration: In certain high-temperature environments, if corrosive gases or liquids exist, the high temperature may accelerate chemical reactions, leading to corrosion of bearing materials and further reducing bearing performance and life.
Clearance management issues: Due to thermal expansion, bearing design must account for proper clearance to avoid increased internal pressure and possible structural damage due to elevated temperatures.
Reliability and maintenance issues: High temperature environments require higher reliability and durability of bearings. At the same time, maintenance and inspection cycles may need to be more frequent to prevent unexpected failures.
Application Scope of Extreme Temperature Deep Groove Ball Bearing
Automotive Industry: High-temperature bearings are used in components such as turbochargers and exhaust systems, which must withstand the intense heat generated by engine operation.
Manufacturing and Processing: In manufacturing processes involving high-temperature furnaces, kilns, or ovens, these bearings ensure smooth operation and reduce the risk of equipment failure.
Aerospace Applications: High-temperature bearings are widely used in jet engines, spacecraft components, and auxiliary power units.
Wind Energy: Bearings in wind turbines, especially those in gearboxes, must operate efficiently under varying temperatures. High-temperature bearings ensure that turbines can handle temperature fluctuations and continue to generate power effectively.
