Spherical multipole moments — are the coefficients in a series expansionof a potential that varies inversely with the distance R to a source, i.e., as frac{1}{R}. Examples of such potentials are the electric potential, the magnetic potential and the gravitational… … Wikipedia
Axial multipole moments — are a series expansionof the electric potential of acharge distribution localized close to the origin along one Cartesian axis, denoted here as the z axis. However, the axial multipole expansion can also be applied to any potential or field that… … Wikipedia
Spherical bearing — A spherical bearing is a bearing that permits angular rotation about a central point in two orthogonal directions within a specified angular limit based on the bearing geometry. Typically these bearings support a rotating shaft in the [bore] of… … Wikipedia

Rolling-element bearing — A rolling element bearing is a bearing which carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding.One of… … Wikipedia
