Appliions: Industrial - Selecting Bronze Bearing Materials

A sleeve bearing''s operating mode is described in terms of a bearing characteristic nuer. A. The value of A, in relation to other factors, determines whether or not the bearing will operate hydrodynamically. The characteristic nuer is calculated by means of the equation: A = m 2 W/D 2 ZN. in which, m = 1000 * 2C/D.
