Abstract
Abstract A thrust bearing race is disclosed which employs lanced tabs to retain the cage assembly. The structure of the tabs facilitate assembly and provide improved retention of the assembly. Cut-outs in the flange are also provided to improve lubrication and provide clearance at assembly.

Claim 5
Dependent Claim
17 words
The thrust bearing race of claim 1 further comprising at least one peripheral aperture in the flange.
Claim 6
Dependent Claim
17 words
The thrust bearing race of claim 2 wherein three lanced tabs are unequally spaced around the flange.
Claim 7
Dependent Claim
21 words
The thrust bearing race of claim 3 further comprising a coined area in the flange between each tab and the raceway.
Claim 8
Dependent Claim
14 words
The thrust bearing race of claim 4 wherein the lance comprises a single cut.
Claim 9
Dependent Claim
16 words
The thrust bearing race of claim 4 wherein the lance comprises a plurality of straight cuts.
Claim 10
Dependent Claim
85 words
A thrust bearing assembly having a cage, rolling elements, and a first race comprising a radially extending annular raceway having inner and outer diameters, a flange integral with and projectinG axially from the outer diameter of the raceway, and at least one lanced tab projecting from from the free edge of the flange inwardly and axially toward the raceway whereby the cage and rolling elements are snapped into position between the raceway and tabs, and axial movement of the cage and rolling elements is restrained.
Claim 11
Dependent Claim
85 words
A thrust bearing assembly having a cage, rolling elements, and a first race comprising a radially extending annular raceway having inner and outer diameters, a flange integral with and projectinG axially from the outer diameter of the raceway, and at least one lanced tab projecting from from the free edge of the flange inwardly and axially toward the raceway whereby the cage and rolling elements are snapped into position between the raceway and tabs, and axial movement of the cage and rolling elements is restrained.
Claim 12
Dependent Claim
30 words
The thrust bearing assembly of claim 7, wherein the free edge of the flange is intermediate the plane described by exposed faces of the rolling elements and said annular raceway.
Claim 13
Dependent Claim
27 words

Claim 20
Independent Claim
92 words
The method of making a thrust bearing race comprising the steps of: stamping an annular blank having a body with an inner and outer diameter; coining at least one area near the outer diameter; lancing the blank between at least one coined area and the outer diameter to create a tab having its separated end radially inward of its integral end; and forming an axial flange along the outer diameter that includes the coined areas and lanced tabs whereby the tabs are inwardly axially directed from the flange toward the annular body.
Claim 21
Independent Claim
92 words
The method of making a thrust bearing race comprising the steps of: stamping an annular blank having a body with an inner and outer diameter; coining at least one area near the outer diameter; lancing the blank between at least one coined area and the outer diameter to create a tab having its separated end radially inward of its integral end; and forming an axial flange along the outer diameter that includes the coined areas and lanced tabs whereby the tabs are inwardly axially directed from the flange toward the annular body.
Claim 22
Independent Claim
79 words
The method of making a thrust bearing race comprising the steps of: blanking an annular body with an inner and outer diameter and at least one coined area near the outer diameter; forming an axial flange at the outer diameter; and lancing the flange between at least one coined area and the free edge of the flange to create a tab having its separated end radially inward of its integral end and inwardly axially directed toward the annular body.
Claim 23
Independent Claim
79 words
The method of making a thrust bearing race comprising the steps of: blanking an annular body with an inner and outer diameter and at least one coined area near the outer diameter; forming an axial flange at the outer diameter; and lancing the flange between at least one coined area and the free edge of the flange to create a tab having its separated end radially inward of its integral end and inwardly axially directed toward the annular body.
