The Timken Company is a manufacturer of ball bearings used for high precision applications in markets such as aerospace, agriculture, construction, health, machine tool and general industries. Timken standard radial ball bearings consist of an inner and outer ring with a cage of precisions balls. This type of deep groove design has a construction that can handle radial and axial loads in high speed applications. Timken Fafnir precision angular ball bearings are designed for radial and axial loading in single row and double configurations. The Timken line of precision ball bearings includes type MMX machine tool designs for ultra high speed grinding spindles, type HX for excellent running accuracy, ceramic styles with steel rings, and precision miniature types for ultra precision applications. Timken also manufactures Fafnir super precision, Fafnir screw support and Fafnir ceramic ball bearings. Fafnir housed units are also available.

Applications include precision spindles, machine tools, index tables, truck cranes, and radar mounts. 4 point ball bearings are angular contact single row  and can be designed for heavy industrial requirements for large slewing-type applications.

NBK is a manufacturer of deep groove ball bearings designed for radial loads and moderate axial loads. They offer less coefficient of friction, less vibration and noise, less energy consumption, high limiting speed, large size range and variations of structure. NBK's TEX Series ball bearings offer a wide bore and outside diameter range, and use a steel ball. Their 6000 Series also offer a wide inner and outer diameter range in nearly any type you need. Likewise with their R Series and 1600 Series bearings. They each offer a vast inner and outer diameter range and come in nearly every type.
