Abstract
In the present paper we formulate a set of equations for logarithmic spiral grooves on a spherical bearing. The grooves satisfy the condition that the angle between the velocity vector and the tangent to the groove remains constant. A procedure is briefly described to make grooves on a spherical ball. The results are then compared with those obtained using a simple equation for spiral grooves. It is found that the shape of the grooves and the axial load capacity of the bearings are not significantly different in the two cases.
