Abstract
Abstract A bearing configuration is presented wherein the races are a hard metal, such as steel, coated with a soft metal, such as silver; the bearing elements are a hard metal insoluble with the race coating material, such as stainless steel; and the retainer is a polymeric material filled with a metallic sulfide, such as MoS2, which bonds to the race coating material.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A bearing assembly including: an inner race element having a raceway therein; an outer race element having a raceway therein; a coating of metal on the raceway of each of said inner and outer race elements, said coating being of a material softer than the material of said raceways; a plurality of bearing elements between said race elements, said bearing elements being of a material insoluble with said metal coated on said races; and retainer means for retaining said bearing elements, said retainer means being composed of a polymeric material filled with a metallic sulfide which has an affinity for said metal coated on said races.
Claim 2
Dependent Claim
106 words
A bearing assembly including: an inner race element having a raceway therein; an outer race element having a raceway therein; a coating of metal on the raceway of each of said inner and outer race elements, said coating being of a material softer than the material of said raceways; a plurality of bearing elements between said race elements, said bearing elements being of a material insoluble with said metal coated on said races; and retainer means for retaining said bearing elements, said retainer means being composed of a polymeric material filled with a metallic sulfide which has an affinity for said metal coated on said races.
Claim 3
Dependent Claim
31 words
A bearing assembly as in claim 1 wherein: said coating of metal on said raceways is of a thickness from 25 X 10 6 inches to 25 X 10 6 inches.
Claim 4
Dependent Claim
23 words
A bearing assembly as in claim 1 wherein: said metallic sulfide comprises from 2 to 5 percent, by weight of said retainer means.
Claim 5
Dependent Claim
92 words
A bearing assembly including: an inner race element having a raceway therein; an outer race element having a raceway therein; a coating of silver on each of said raceways, said silver coating being softer than the material of the raceways on which it is coated; a plurality of bearing elements between said race elements, said bearing elements being of a material insoluble with silver; and retainer means for retaining said bearing elements, said retainer means being composed of a polymeric material filled with a metallic sulfide which has an affinity for silver.
Claim 6
Dependent Claim
92 words
A bearing assembly including: an inner race element having a raceway therein; an outer race element having a raceway therein; a coating of silver on each of said raceways, said silver coating being softer than the material of the raceways on which it is coated; a plurality of bearing elements between said race elements, said bearing elements being of a material insoluble with silver; and retainer means for retaining said bearing elements, said retainer means being composed of a polymeric material filled with a metallic sulfide which has an affinity for silver.
Claim 7
Dependent Claim
22 words
A bearing assembly as in claim 4 wherein: said bearing elements are stainless steel and said race elements are a steel alloy.
Claim 8
Dependent Claim
24 words
A bearing assembly as in claim 4 wherein: said silver coating is from 25 X 10 6 inches to 250 X 10 6 inches.
Claim 9
Dependent Claim
16 words
A bearing assembly as in claim 6 wherein: said silver coating is approximately 0.0001 inches thick.
Claim 10
Dependent Claim
23 words
A bearing assembly as in claim 4 wherein: said metallic sulfide comprises from 2 to 50 percent by weight of said retainer means.
Claim 11
Dependent Claim
14 words
