Aerospace & Defense

Providing optimal reliability in critical applications:
Through advanced aircraft bearing solutions.

An expansive tiered portfolio for specialized applications.

Whether the inherent challenges involve long life, heavy loads, extreme speeds/temperatures, limited space, simplified assembly — or any combination of these critical variables — NHBB continues to serve the aerospace and defense industries with reliable, application-specific solutions.


NHBB design/production processes are specifically engineered to serve the exacting needs of aircraft manufacturers and their customers, our most important market. Our specialized knowledge, coupled with sustained product development investments, enables us to assist aerospace OEMs in solving complex design issues for airplanes and helicopters.


Founded to improve the manufacturing of precision miniature ball bearings, NHBB quickly became a partner-of-choice for manufacturers of components and assemblies for military applications. Our continually evolving capabilities now provide even greater precision and fail-safe performance across a wider array of defense applications.
