Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
A self-supporting half-cylindrical plain bearing comprising a part-cylindrical journal shell and a separate part-annular end flange located radially and axially in relation to the shell by engagement in an annular recess in the back of the shell at one end and located circumferentially by co-operating shoulders on at least one notch in the shell and at least one lug on the flange, the edge of said flange being located in said recess.
Claim 2
Dependent Claim
72 words
A self-supporting half-cylindrical plain bearing comprising a part-cylindrical journal shell and a separate part-annular end flange located radially and axially in relation to the shell by engagement in an annular recess in the back of the shell at one end and located circumferentially by co-operating shoulders on at least one notch in the shell and at least one lug on the flange, the edge of said flange being located in said recess.
Claim 3
Dependent Claim
18 words
A bearing as claimed in claim 1 in which the recess comprises a groove having axially separated sides.
Claim 4
Dependent Claim
33 words
A bearing as claimed in claim 1 in which the whole length of the radially inner edge of the flange other than the portion at the lug or lugs lies in the groove.
Claim 5

A bearing as claimed in claim 1 in which each lug extends radially inwardly from the flange.
Claim 9
Dependent Claim
27 words
A bearing as claimed in claim 7 in which the lug has been deformed after assembly of the flange in the shell into the circumferential location position.
Claim 10
Dependent Claim
18 words
A bearing as claimed in claim 1 in which the said end of the shell tapers axially outwards.
Claim 11
Dependent Claim
18 words
