High-temperature Bearings

High temperature bearings are industrial bearings engineered to operate reliably in environments ranging from 300°C to 800°C where standard bearings fail due to lubrication breakdown, thermal expansion, and material instability.

Our high temperature bearings are designed for furnaces, kilns, steel processing lines, drying systems, and heat treatment equipment requiring stable operation under continuous heat exposure. Solutions include grease-lubricated designs, solid lubrication systems, and full ceramic bearing structures for demanding industrial applications.

High Temperature Bearing Types

Deep Groove Ball Bearings

Deep groove ball bearings for high temperature environments are commonly used in conveyors, motors, fans, and processing equipment where stable rotation and heat resistance are required.

Solid Lubrication Bearings

Solid lubrication bearings are designed for applications where conventional grease lubrication fails due to elevated temperatures. These bearings are widely used in ovens, dryers, and heat treatment systems.

Full Ceramic Bearings

Full ceramic bearings using Si3N4 ceramic balls and advanced ceramic structures provide excellent resistance to corrosion, thermal shock, and lubrication failure in extreme heat environments.

High Temperature Bearings for Industrial Applications

Furnace Conveyor Systems

High temperature bearings used in furnace conveyor systems must withstand continuous heat exposure while maintaining dimensional stability and low maintenance requirements. Solid lubrication and ceramic structures help reduce lubrication failure in high heat environments.

Steel Processing Equipment

Heat resistant bearings are widely used in steel mills, rolling lines, and continuous casting systems where thermal expansion and heavy loads can rapidly damage conventional bearing structures.

Kilns and Drying Systems

High heat bearings for kilns and drying systems require reliable sealing performance, thermal stability, and resistance to contamination under elevated operating temperatures.

Heat Treatment Equipment

Bearings for high temperature applications in annealing and heat treatment systems often require solid lubrication or dry running capability to improve service life and reduce maintenance downtime.

How to Select High Temperature Bearings

Selecting the correct high temperature bearing depends on operating temperature, rotational speed, load conditions, lubrication method, contamination exposure, and internal clearance requirements such as C3, C4, or C5 configurations.

Common Causes of High Temperature Bearing Failure

Lubrication failure remains one of the leading causes of damage in high temperature bearings, especially in furnace conveyor systems, steel processing equipment, and industrial heat applications.

Typical Furnace Conveyor Bearing Challenges

In continuous furnace conveyor systems, standard grease-lubricated bearings often fail due to lubricant carbonization and thermal expansion. Solid lubrication bearings and ceramic high temperature bearings help reduce maintenance frequency and improve operating reliability under elevated temperatures.
