What Are High Temperature Bearings?

High temperature bearings are advanced mechanical components designed to operate reliably in environments where standard bearings would fail due to heat. These bearings can function effectively at temperatures up to 350°C (662°F) or higher, thanks to specialized materials, lubricants, and clearances.

Whether in steel production or food processing, high temp bearings ensure smooth, efficient machinery operation without failure—even in prolonged high-heat applications.

Types of High Temperature Bearings

Choosing the right bearing type is essential for maximum performance. Common types include:

Deep Groove Ball Bearings

Ideal for high-speed applications and stable under both radial and axial loads at elevated temperatures.

Cylindrical Roller Bearings

Engineered for heavy radial loads in extreme heat—frequently used in kilns, furnaces, and steel mills.

Spherical Roller Bearings

Accommodate misalignment while handling intense heat and load. Widely used in mining and cement industries.

Self-Aligning Ball Bearings

Perform well in environments with shaft deflection and high operating temperatures.

Needle Roller Bearings

Compact and capable of handling high-speed and high-temperature conditions with minimal space.

Key Features of High Temp Bearings

  • Heat-Resistant Materials: Stainless steel, high-chromium alloys, or ceramics prevent deformation under thermal stress.
  • High Temperature Lubrication: Solid lubricants (graphite, MoS₂) or synthetic high-temp greases ensure longevity.
  • Protective Seals: Reduce contamination and maintain lubricant integrity.
  • Thermal Clearance Design: Adjusted internal clearances prevent jamming due to thermal expansion.
  • Corrosion Resistance: Surface treatments protect against oxidation in hot, humid environments.

Applications of High Temperature Bearings

  • Metallurgy & Foundry: Continuous casters, hot strip mills.
  • Food & Beverage: Ovens, dryers, sterilization systems.
  • Glass & Ceramics: Kilns, conveyor systems.
  • Automotive & Aerospace: Exhaust assemblies, turbo systems.
  • Plastics & Textiles: Drying equipment, heated rollers.
