A gyratory crusher comprises an eccentric (10) having an inner slide bearing surface and an outer slide bearing surface, the inner slide bearing surface defining, together with an opposing slide bearing surface, an inner slide bearing (34), and the outer slide bearing surface defining, together with another opposing slide bearing surface, an outer slide bearing (38), the eccentric (10) being rotatably connected to a crusher frame (4) so as to allow a rotation about an eccentric axis of rotation (C) which is fixed relative to the frame (4), the eccentric axis of rotation (C) being defined by one of said inner and outer slide bearings (34, 38); and wherein the inner slide bearing (34) has a total height-to-diameter quotient (H1/D1) of less than 1.0. |
