Radial Load - A load applied normal to the
bearing bore axis.
Axial Load - A load applied along the bearing bore axis.
Static Radial Limit Load - That static load required to produce a
specified permanent set in the beginning structure. It will vary for a given
size as a function of configuration. It may also be pin limited or it may be
limited as a function of body restraints, as in the case of a rod end
bearing.
Static Radial Ultimate Load - That load that can be applied to a
bearing without fracturing the ball, race or rod end eye. The ultimate load
rating is usually but not always 1.5 times the limit load.
Static Axial Limit Load - That load that can be applied to a bearing
to produce a specified permanent set in the bearing structure.
Static Axial Ultimate Load - That load that can be applied to a
bearing without separating the ball from therace. the ultimate load rating
is usually but not always 1.5 time the limit load.
Axial Proof Load - That axial load that can be applied to a mounted
spherical bearing without imparing the integrity of the bearing mounting or
bearing performance. It is always less than the static axial limit load.
Oscillating Radial Load - A unidirectional load producing a
specified maximum amount of wear when the bearing is oscillated at a
specific frequency and amplitude.
