A gyratory crusher bearing includes a bearing surface to support rotational movement of a crushing head, wherein a shape profile of the bearing surface at a cross section of the bearing perpendicular to a longitudinal axis of the bearing is substantially circular. A mounting surface is positioned against a bearing support and is orientated to be outward facing relative to the longitudinal axis. A bearing wall is defined between the mounting surface and the bearing surface, the bearing surface defining a central bore extending between a first edge end and a second edge end of the wall. At least one region of the mounting surface in combination with the bearing surface defines the wall between the first edge end and the second edge end and includes a shape profile at a cross section of the bearing perpendicular to the longitudinal axis that is non-circular to define an anchorage region to inhibit rotation of the bearing about the longitudinal axis relative to the bearing support.
