Abstract
A bearing including a sidewall including a substrate and a low friction material extending along at least one of a radially inner surface or a radially outer surface of the sidewall, the sidewall further including: a body defining a bore about a central axis; and a flange contiguous with and extending from an axial end of the body, where the flange includes a folded over outermost peripheral edge, where the substrate has a reduced thickness at the outermost peripheral edge, the flange being configured such that the substrate is not exposed along the outermost peripheral edge.
Claims12
A bearing comprising:
- a sidewall comprising:
- a body comprising a substrate and defining a bore about a central axis;
- and
- a reduced thickness portion at an axial end of the body, wherein the reduced thickness portion is folded over to define a flange comprising an outermost peripheral edge, wherein a low friction material overlies and at least partially encapsulates the substrate at the outermost peripheral edge so that the substrate is not exposed along the outermost peripheral edge, wherein α thickness of the flange is substantially the same as a thickness of the body portion.
An assembly comprising:
- an inner component;
- an outer component;
- and
- a bearing disposed radially between the inner component and the outer component, wherein the bearing comprises:
- a sidewall comprising:
- a body comprising a substrate and defining a bore about a central axis;
- and
- a reduced thickness portion at an axial end of the body, wherein the reduced thickness portion is folded over to define a flange comprising an outermost peripheral edge, wherein a low friction material overlies and at least partially encapsulates the substrate at the outermost peripheral edge so that the substrate is not exposed along the outermost peripheral edge, wherein α thickness of the flange is substantially the same as a thickness of the body portion.
A method comprising:
- providing a blank comprising a substrate and a low friction material;
- forming the blank into a sidewall comprising a body defining a bore about a central axis, wherein the low friction material extends along at least one of a radially inner surface or a radially outer surface of the sidewall;
- chamfering the substrate at an axial edge of the sidewall so that the substrate has a reduced thickness;
- folding over the chamfered axial edge of the sidewall;
- and
- stamping the axial edge of the sidewall to form a flange contiguous extending from the bore of the sidewall, wherein the substrate is not exposed along an outermost peripheral edge, wherein the low friction material overlies and at least partially encapsulates the substrate at the outermost peripheral edge.
