fluid film bearings technical

"a global leader in the design and manufacture of advanced fluid film bearings and magnetic"

Fluid film bearings are machine parts that support rotating shafts by keeping them separated from their housings on a thin layer of oil or other fluid, so the moving surfaces never touch. For investors, they matter because they improve efficiency, reduce wear and maintenance, extend equipment life and lower the risk of costly downtime—factors that affect operating costs, capital spending and the reliability of companies that rely on heavy machinery.

magnetic bearing systems technical

"design and manufacture of advanced fluid film bearings and magnetic bearing systems, today an"

Magnetic bearing systems use controlled magnetic fields to hold a rotating shaft in place without physical contact, so the parts “float” instead of rubbing together like wheels on an axle. For investors, they matter because this contact-free design can cut energy use, reduce maintenance and downtime, and extend equipment life—potentially lowering costs and improving reliability for companies that rely on high-speed or continuous machinery.

nacelle technical

"pad shape allows for straightforward integration into the nacelle, simplifying installation whet"

A nacelle is the streamlined housing that holds critical machinery — on airplanes it covers engines and related systems, and on wind turbines it contains the gearbox, generator and control equipment. Like the engine room of a ship, it protects key components from weather and makes maintenance access easier, so its design, durability and weight directly affect operating costs, downtime and performance — all important factors for investors tracking capital and revenue risks.

DOWNERS GROVE, Ill., April 22, 2026 /PRNewswire/ -- Waukesha Bearings, part of Dover Precision Components and Dover (NYSE: DOV) and a global leader in the design and manufacture of advanced fluid film bearings and magnetic bearing systems, today announced the launch of the NordAlign™ bearing, specifically engineered for wind turbine main shafts. This groundbreaking technology is designed to enhance turbine reliability, reduce maintenance costs, and streamline installation.

"Waukesha Bearings is committed to advancing technologies that not only improve efficiency and performance but also reduce operational costs for our customers," said Chris Johnson, VP and General Manager of Engineered Bearings. "The introduction of the NordAlign bearing represents a significant step forward in wind turbine technology and aligns with our mission to deliver innovative solutions that meet the evolving needs of the renewable energy sector."

NordAlign bearings are built for durability and reliability, often outlasting existing main bearing options. Tilt pads dynamically adjust to both radial and axial shaft movements, helping optimize load distribution and extending lifespan. When maintenance and repairs are required, NordAlign bearing pads can be replaced uptower, eliminating the need for expensive jack-up vessels and cranes. The modular design easily scales to accommodate larger wind turbine models, while the optimized pad shape allows for straightforward integration into the nacelle, simplifying installation whether retrofitted to existing equipment or installed in a new application.

NordAlign bearings deliver high performance across a wide range of operating conditions, including assembly, low-speed idling, and extreme events. To meet the unique demands of wind applications, Waukesha Bearings uses its in-house materials development and testing expertise to create TruTech® engineered polymer, specially formulated to maximize wear resistance and enhance performance, even in harsh operating environments.
