Patent ID: 8430570

Claim:
A method comprising assigning a plurality of bearing components to a plurality of tolerance classes, wherein the plurality of bearing components comprise: a plurality of bearing bores, a plurality of journals, a plurality of upper bearing shells, and a plurality of lower bearing shells, wherein a first value (M 1 ) is defined as a difference between a diameter of a bearing bore (D) and a thickness of a upper bearing shell (LS), when the bearing bore and the upper bearing shell are assigned to the same tolerance class, wherein a second value (M 2 ) is defined as a sum of the diameter of a journal (d) and a thickness of a lower bearing shell (Is), when the journal and the lower bearing shell are assigned to the same tolerance class, wherein a maximum value of the first value (M 1 ) is the same for all of the plurality of tolerance classes, wherein a minimum value of the first value (M 1 ) is the same for all of the plurality of tolerance classes, wherein a maximum value of the second value (M 2 ) is the same for all of the plurality of tolerance classes, wherein a minimum value of the second value (M 2 ) is the same for all of the plurality of tolerance classes, assembling a first component selected from the group consisting of a bearing bore, a journal, and combinations thereof together with a second component selected from the group consisting of an upper bearing shell, a lower bearing shell, and combinations thereof to form a bearing, wherein the first component belongs a first tolerance class from the plurality of tolerance classes, wherein the second component belongs to a second tolerance class from the plurality of tolerance classes, and wherein the first tolerance class is different from the second tolerance class.
