1. A method for producing a bearing body, comprising the steps of:
producing, on a surface of a metallic main body, a plurality of protrusions extending outward from the surface of the main body, each of the plurality of protrusions extending in a longitudinal direction from the main body to a surface of the protrusion that is distal from the main body; and
subsequently, machining each of the plurality of protrusions to define a through-bore that extends transversely through the protrusion relative to the longitudinal direction of the protrusion, such that each protrusion includes a contour for anchoring a sliding coating.
 
6. A metallic bearing body for a sliding bearing, comprising:
a plurality of protrusions located on the surface of a main body of the bearing body and formed in one piece from the main body of the bearing body, wherein the plurality of protrusions each have at least one through-bore running therethrough in a direction that is not parallel to a longitudinal direction of the protrusion.
 
11. A metallic bearing body for a sliding bearing, comprising:
a main body; and
a plurality of protrusions extending outward from the main body, each of the plurality of protrusions extending in a longitudinal direction from the main body to an upper surface that is distal from the main body and having at least one through-bore that extends through the protrusion transversely relative to the longitudinal direction.
