Definition
Bearings designed to operate under temperatures that exceed the limits of standard bearings. They utilize special steels, heat treatments, surface coatings, and high- temperature lubricants to maintain load capacity, dimensional stability, and low friction in extreme environments.
Features
- Heat resistance depending on bearing type (typically 150 °C to 300 °C, or higher for special designs)
- Stable dimensional accuracy under prolonged thermal load
- Enhanced resistance to oxidation and corrosion
- Use of special high -temperature lubricants or lubrication-free variants
- Reduced internal stress thanks to heat-treated materials
- Suitable for continuous operation in thermally demanding systems
- Available in ball, roller, spherical, and special configurations
Applications
- Furnaces, ceramic and metallurgical processing lines
- Industrial dryers and calenders
- Conveyors operating in high- temperature zones
- Motors, fans, and pumps exposed to prolonged heat
- Chemical industry and power generation
- Applications where standard bearings lose strength or lubricants degrade
Conclusion
High temperature bearings are the ideal solution for applications requiring consistent performance under prolonged exposure to extreme heat. Their construction and materials prevent deformation, lubricant breakdown, and extend equipment life in demanding operating conditions.
