JFK high-temperature bearings
JFK ball bearings
- Resistance up to +330°C
- Specialized materials and lubricants
- Reduced maintenance
High-temperature bearings are rolling bearings made with specialized materials, heat treatments, and lubricants designed to operate at temperatures up to +330°C while maintaining dimensional stability and load capacity. In applications involving furnaces, heat-treatment lines, or heat sources, standard bearings can quickly lose performance, leading to premature wear, reduced efficiency, and machine downtime. JFK high-temperature bearings maintain smooth operation thanks to materials, treatments, and lubricants specifically selected for high-temperature conditions.
The JFK range of high-temperature ball bearings covers applications up to +330°C, with dimensional stability ensured by heat treatments and wear resistance maintained even under load. These heat-resistant bearings significantly reduce maintenance requirements and downtime compared with standard bearings, while remaining reliable under the most severe thermal conditions.
Performances
Design and performance features
Specialized materials, heat treatments, and lubricants to ensure consistent performance even under the most demanding thermal conditions.
Temperature
Heat-resistant bearings designed to operate at elevated temperatures while maintaining reliability and consistent performance. Dimensional stability is ensured by dedicated heat treatments.
High wear resistance under load
High-temperature bearings offer a longer service life than standard bearings under high-temperature operating conditions. High wear resistance and continuous operation even under severe working conditions.
Specialized high-temperature lubricants
The use of high-temperature lubricants helps maintain performance over time and reduce maintenance requirements, even in thermally demanding environments.
Reduced maintenance requirements
The use of specialized materials and lubricants helps reduce maintenance requirements and plant downtime compared with standard bearings.
Safety and operational continuity
They help improve production efficiency, operational stability, and plant safety, even in applications exposed to severe thermal stress.
Mounting
Installation of high-temperature bearings
Installation follows the same practice used for standard deep groove ball bearings, with the additional care of using lubricants and, where applicable, seals compatible with the entire specified operating temperature range (up to +330°C).
Mounting methods
- Heating the inner ringFor larger bearings, use oil-bath or induction heating, ensuring that the heating temperature does not compromise the specialized high-temperature lubricant already present.

Applications
Applications
Components and application support for every industrial environment.
Industrial automation
Production facilities with heat sources, heat-treatment lines, and material handling systems exposed to high temperatures. High-temperature bearings ensure operational continuity without unplanned downtime.
Metal Fabrication / Machining Industry
Industrial furnaces, metal heat-treatment plants, and high-temperature processing lines. Resistance up to +330°C covers the most demanding operating conditions in the metalworking industry.
Construction Equipment
Material handling systems exposed to severe thermal stress in demanding industrial environments. Longer service life reduces machine downtime and maintenance costs.
Transmissions and axles
Gearboxes and transmission systems located near heat sources or operating at elevated temperatures, where standard bearings cannot provide the required service life.Technical documents
