Abstract

Bearings for earth-boring tools may include a first bearing member including a first bearing pad having a first contact surface and a second bearing member including a second bearing pad having a second contact surface in sliding contact with at least a portion of the first contact surface. At least one of the first bearing member and the second bearing member may include a polycrystalline table attached to a portion of a first substrate on which the polycrystalline table was formed. Another substrate may be attached to the portion of the first substrate, the portion of the first substrate interposed between the polycrystalline table and the other substrate. The portion of the first substrate may include a first volume percentage of the first matrix material and the other substrate may include a second, different volume percentage of the second matrix material
