Why Lubron AE? Nuclear Qualified. Radiation Resistant. Built to Last.
Lubron AE bearings were developed for applications where conventional lubrication is impractical and failure is not an option. Permanently embedded near-isotropic graphite lubricants provide continuous self-lubrication while withstanding extreme temperatures, neutron irradiation, and gamma radiation exposure.
The combination of nuclear-grade graphite and premium bearing alloys delivers exceptional wear resistance, dimensional stability, and low friction under slow-to-medium speed operating conditions. Trusted by nuclear utilities, engineering firms, and power generation facilities worldwide, Lubron AE bearings provide long service life and reliable performance in the most demanding environments.
Key Features
-
Designed for nuclear service, Lubron AE utilizes near-isotropic nuclear-grade graphite lubricants with impurity levels below 100 ppm, providing excellent dimensional stability and performance under neutron and gamma radiation exposure.
-
Available with lubricant systems capable of operating at temperatures up to 2000°F (1093°C), making Lubron AE suitable for extreme thermal environments.
-
Embedded graphite lubricants provide continuous lubrication throughout the bearing's service life, eliminating the need for routine grease or oil maintenance.
-
Premium bronze and Meehanite bearing alloys support demanding applications with design loads up to 8,000 psi, while maintaining excellent structural integrity and wear resistance.
-
Typical coefficients of friction between 0.10 and 0.15 minimize startup resistance, reduce wear, and ensure smooth operation under heavy loads.
-
Engineered to absorb stresses caused by thermal expansion, structural deflection, and seismic activity while maintaining reliable bearing performance.
-
Designed for dependable operation in both dry environments and demineralized water applications commonly found in nuclear facilities.
-
Specified by nuclear power authorities, public utilities, and engineering firms worldwide for critical applications where maintenance access is limited and operational reliability is essential.
Installation:
LUBRON AE bearings are supplied fully machined and ready for installation. Bushings are typically press-fit or chill-fit into the housing using a controlled interference fit. Because installation slightly reduces the bearing inside diameter, proper clearances are incorporated into the design to ensure optimum running performance. Care should be taken to protect lubricated surfaces and maintain proper alignment during installation.
