Bearing Solutions for Wind and Nuclear Power Systems

Kingsbury Hydrodynamic Bearings are engineered for long-term performance in the most demanding renewable and low-emission energy systems. In both wind and nuclear applications, our bearings deliver the load capacity, thermal stability, and service life required to keep critical equipment online, often for decades without replacement.

We work directly with OEMs, utilities, and plant engineers to design, manufacture, and support bearing systems that meet the specific mechanical and operational demands of each installation. Whether you’re managing high-speed turbine shafts or slow-speed reactor coolant pumps, Kingsbury bearings are built to perform under pressure.

Nuclear-Grade Bearings for Reactor and Auxiliary Systems

Kingsbury bearings are installed in nuclear power plants across the U.S., including in reactor coolant pumps, feedwater pumps, turbine generators, and auxiliary systems. These applications demand absolute reliability, often under extreme thermal and radiation conditions.

Our nuclear-qualified bearings are:

• Manufactured to ASME and RCC-M standards
• Available in high-temperature babbitt or polymer-lined configurations
• Designed for low-vibration, low-wear operation over multi-decade lifespans
• Supported by full traceability, documentation, and QA/QC protocols

 In one case, a nuclear plant experiencing elevated vibration in a vertical pump traced the issue to uneven pad loading. A Kingsbury self-equalizing retrofit restored balance and reduced vibration levels by over 40%, verified through post-installation monitoring.

Engineering Support from Design to Decommissioning

Kingsbury supports the full lifecycle of your equipment.

Our services include:

• Custom bearing design and application engineering
• Failure analysis and root cause investigation
• Reverse engineering and drop-in replacements
• On-site inspection, installation, and commissioning

We’ve supported nuclear plants through license extensions and wind farms through drivetrain redesigns. Our engineers understand the regulatory, operational, and mechanical realities of these industries, and we build that knowledge into every solution we deliver.

Why Kingsbury

Kingsbury invented the tilting pad bearing and continues to lead in hydrodynamic bearing innovation.

For wind and nuclear power systems, we offer:

• U.S.-based manufacturing with full material traceability
• Decades of field-proven performance in critical systems
• Responsive engineering support and field service teams

Whether you need a new design, a repair plan, or on-site help, Kingsbury is built to support critical systems for the long haul.
