Abstract
Official abstract text for this publication.
A bearing assembly includes at least one inner ring and at least one outer ring, and at least one surface of the inner or outer ring is partially colored with an acid-free ink. If the at least one surface includes a surface defect such as a scratch in a black-oxide coating, the acid-free ink may be applied to the scratch to at least partially conceal it.
First claim
Opening claim text (preview).
What is claimed is: 1. A bearing assembly comprising: at least one inner ring, and at least one outer ring, wherein at least one surface of the inner ring and/or at least one surface of the outer ring is partially colored with an acid-free ink. 2. The bearing assembly according to claim 1 , wherein the at least one surface of the inner ring and/or the at least one surface of the outer ring includes a black-oxidized layer having a surface defect and wherein the surface defect is coated with the acid-free ink. 3. The bearing assembly according to claim 1 , wherein the acid-free ink includes organic solvents, colorants, and binders. 4. The bearing assembly according to claim 3 , wherein the acid-free ink includes 85-90% solvents. 5. The bearing assembly according to claim 4 , wherein the solvents include butanone, 2-butanone, and/or ethyl methyl ketone. 6. The bearing assembly according to claim 3 , wherein the black-oxidized surface has a color and wherein the colorant is selected to match the color. 7. The bearing assembly according to claim 2 , wherein the surface defect is a scratch in the black-oxidized layer. 8. The bearing assembly according to claim 1 , wherein the at least one surface of the inner ring and/or the at least one surface of the outer ring includes a black-oxidized layer having a scratch, wherein the scratch is coated with the acid-free ink, wherein the acid-free ink includes organic solvents, colorants, and binders, wherein the solvents include butanone, 2-butanone, and/or ethyl methyl ketone, and wherein the black-oxidized surface has a color and wherein the colorant is selected to match the color.
