A gyratory crusher comprising a crushing head on which a first crushing shell is mounted, the crushing head mounted on a crushing head shaft which is arranged in a top spider; a frame on which a second crushing shell is mounted, which second crushing shell defines, together with the first crushing shell, a crushing gap; and an eccentric 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, and the outer slide bearing surface defining, together with another opposing slide bearing surface, an outer slide bearing, the eccentric being rotatably connected to the frame so as to allow a rotation about an eccentric axis of rotation relative to the frame, the eccentric axis of rotation being defined by one of said inner and outer slide bearings (34, 38), the inner slide bearing having an inner bearing lining and the outer slide bearing having an outer bearing lining both arranged on the eccentric; the crushing head being rotatably connected to the eccentric so as to allow a rotation about a crushing head axis relative to said eccentric, the crushing head axis of rotation being defined by the other of said inner and outer slide bearings (34, 38), the crushing head thereby being arranged to, when the crusher is operated, execute a gyratory movement about the eccentric axis for crushing of material that is introduced in the crushing gap, characterized in that: the respective inner and outer slide bearings. (34, 38) have a diameter (D1, D2) and a total axial height (H1, H2) defined respectively by an axially upper end (235a, 239a) and an axially lower end (237a, 241a), wherein a quotient of the total axial height to diameter (H1/D1) is less than 1.0 and is larger than 0.35 and a quotient of the total axial height to diameter (H2/D2) is less than 0.5 and larger than 0.15; wherein the inner slide bearing lining has a non-uniform thickness so as to define a circular-cylindrical inner surface which is eccentric with respect to a circular-cylindrical outer surface; and the inner and/or outer slide bearings (34, 38) have a diametral clearance between the respective inner and opposing slide bearing surfaces (46, 44) and the outer and opposing slide bearing surfaces (48, 50) defined as the diameter (D1, D2) of the respective inner and outer slide surfaces (46, 48) multiplied by a relative clearance ξ of between about 2*10 -4 and about 5*10 -3. the respective inner and outer slide bearings. (34, 38) have a diameter (D1, D2) and a total axial height (H1, H2) defined respectively by an axially upper end (235a, 239a) and an axially lower end (237a, 241a), wherein a quotient of the total axial height to diameter (H1/D1) is less than 1.0 and is larger than 0.35 and a quotient of the total axial height to diameter (H2/D2) is less than 0.5 and larger than 0.15; wherein the inner slide bearing lining has a non-uniform thickness so as to define a circular-cylindrical inner surface which is eccentric with respect to a circular-cylindrical outer surface; and the inner and/or outer slide bearings (34, 38) have a diametral clearance between the respective inner and opposing slide bearing surfaces (46, 44) and the outer and opposing slide bearing surfaces (48, 50) defined as the diameter (D1, D2) of the respective inner and outer slide surfaces (46, 48) multiplied by a relative clearance ξ of between about 2*10 -4 and about 5*10 -3.
