The generic term for a bearing used in a mounted assembly such as a pillow block or flange unit.

Also known as fit or radial clearance

The distance between the rolling elements and the bearing races.

Established in 1947 to address the problem of divergent standards for machinery, equipment, goods and services. ISO is a nongovernmental, worldwide federation of national standards bodies from more than 140 countries, one from each country. ISO's mission is to promote the development of standardization and related activities in the world with a view to facilitating the international exchange of goods and services, and to developing cooperation in the spheres of intellectual, scientific, technological and economic activity.

ISO's work results in international agreements which are published as International Standards.

Rather than the acronym IOS, the organization adopted the word Iso. Derived from the Greek isos, iso means equal, and is the root of the prefix iso- in terms such as isometric.
