1. A method of forming a mechanical bearing or a bearing component comprising a substrate bonded to a tribological material by an adhesive comprising hot-melt pressure-sensitive core-shell polymeric particles wherein the hot-melt pressure-sensitive core-shell polymeric particles comprise a core and a shell, the method comprising:
a) applying a composition comprising the hot-melt pressure-sensitive core-shell particles to the tribological material to provide a coated tribological material;
b) heating the coated tribological-material to a temperature of about 150° C. to about 220° C.;
c) contacting the substrate with the tribological material at a point where the composition has been applied to provide a laminated structure; and
d) heating the laminated structure comprising the substrate and the coated tribological material to a temperature of about 345° C. to about 360° C. under 0.1 Pa to 32 MPa pressure.
