Abstract

A lead-free bearing includes a bronze matrix powder metal bearing layer bonded to a steel backing a fully densified. The bearing material has about 8 to 12% by weight tin, about 1 to less than 5% by weight bismuth, and about 0.03 to 0.08% by weight phosphorus, with the balance being copper. The tin is soluable in the copper to yield the bronze matrix, and the bismuth exists as finely dispersed, undissolved islands through the matrix. Such bearings exhibit physical properties comparable to or better than those of traditional bronze-lead bearings and improved wear in seizure properties.

Claims (4)

1. A method of making a lead-free bearing comprising:

applying powder metal bearing material to a steel backing, the bearing material having a composition consisting essentially of 8 to 12% by weight of tin, 1 to less than 5% by weight of bismuth, 0.03 to 0.08% by weight of phosphorus, and the balance consisting essentially of copper; and

rolling and sintering the powder metal bearing material onto the backing to bond the bearing material to the backing and to fully densify the bearing material.

2. The method of claim 1 , including installing the bearing in use and applying friction and load forces to an exposed bearing surface of the bearing material, causing tin from a copper-tin matrix of the bearing material to migrate to the bearing surface to yield a tin-rich layer with the bearing surface.
