    Abstract: An aluminum-lead bearing alloy in continuously cast strip form has a lead content in excess of 1% by volume, 4% by weight. The lead phase consists of uniformly distributed spherical particles no more than 25 microns in diameter, and the content of all other constituents other than aluminum totals not more than 10% by weight, the balance being aluminum. The alloy is used in engine bearings wherein an aluminum-lead alloy lining is bonded to a steel backing.

    Abstract: A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 4% Si, 2% Pb and 1% Cu on a weight percentage basis. The tin has an average particle size less than five microns and the silicon has an average particle size less than 3.5 microns. The alloy is formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip is pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing. During the pressure bonding step the thickness of the aluminum alloy strip is significantly reduced while the thickness of the steel strip remains essentially unchanged.

    Abstract: A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 2.5% Si, 2% Pb, 0.8% Cu and 0.2% Cr on a weight-percentage basis. The tin has an average particle size less than 5 microns and the silicon has an average particle size less than 5 microns. The alloy may be formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip can be pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing.

    Abstract: A bi-metal aluminum bearing includes an aluminum-based bearing layer, a steel backing, and an intermediate aluminum-based layer that has a thickness of from 60 to 120 micrometers positioned between the aluminum-based bearing layer and the steel backing. The intermediate layer has a yield strength that is less than that of the aluminum-based bearing layer and is preferably of pure aluminum. The aluminum-based bearing layer has a fine microstructure which imparts a very high level of conformability while retaining good fatigue strength. The aluminum bearing layer generally includes 4% to 20% by weight lead or tin, up to 26% by weight silicon and up to 2% by weight of any of the elements magnesium, manganese, nickel, zirconium, zinc, copper, or chromium with the remainder of the bearing layer being aluminum.
