RBC Bearings Incorporated

RBC Bearings Incorporated manufactures and markets engineered precision bearings and components in North America, Europe, Asia, and Latin America. It operates through four segments: Plain Bearings, Roller Bearings, Ball Bearings, and Engineered Products. The Plain Bearings segment produces plain bearings with self-lubricating or metal-to-metal designs, including rod end bearings, spherical plain bearings, and journal bearings that are primarily used to rectify inevitable misalignments in various mechanical components, such as aircraft controls, helicopter rotors, or in heavy mining and construction equipment. The Roller Bearings segment offers heavy duty needle roller bearings, tapered roller bearings, track rollers, and aircraft roller bearings, which are anti-friction bearings that use rollers instead of balls. The Ball Bearings segment manufactures high precision aerospace, airframe control, thin section, and commercial ball bearings that utilize high precision ball elements to reduce friction in high speed applications. The Engineered Products segment offers engineered hydraulics and valves for aircraft and submarine applications, and aerospace and defense aftermarket services; fasteners; precision mechanical components, which are used in various general industrial applications; and machine tool collets that are used for holding circulars or rod-like pieces. The company serves the construction and mining, oil and natural resource extraction, heavy truck, marine, rail and train, packaging, semiconductor machinery, wind, canning, and general industrial markets through its direct sales force, as well as a network of industrial and aerospace distributors.
