Abstract
A dry bearing (,, FIG.,(,)) for a hinge pin or the like comprises a bush,mounted in a radially supportive housing (,), the bush being formed by a circumferentially discontinuous tubular form made by rolling a strip of steel-backed, bearing material having a filled polymer infiltrated sintered bronze (ISB) lining about a mandrel (FIG.,(,)). The tubular form is, after mounting and to provide a more uniform inside diameter, burnished by pushing therethrough a burnishing tool (,), having a cylindrical portion (,), of larger diameter than the mounted form. The bearing (and method of manufacture) differ from the art in that a minor part of the lining surface is, prior to passage of the burnishing tool and conveniently when still in strip form, compressed in part as depressions (troughs,) arrayed over the surface. Such depressions permit burnishing with a less oversize tool to get said uniform inside diameter, thereby requiring less work in driving the tool and with less risk of shearing the lining components and damaging the surrounding housing with radial pressure during burnishing.
