TRW is the worlds leading premium solution for braking, steering and suspension. With over 100 years' experience as an Original Equipment provider we write the standards for safety and quality.The Gurney Ball Bearing Company, on the other hand, was founded in 1902 by Frederick W. Gurney in Jamestown, New York. In 1905, Frederick Gurney introduced the Gurney "radial-thrust angular-contact" bearing then the Gurney "radial-Type R" bearing four years later. In addition, Gurney developed duplex bearings.

Bearings are highly engineered, precision-made components that enable machinery to move at extremely high speeds and carry remarkable loads with ease and efficiency. Bearings must be able to offer high precision, reliability and durability.A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.
