1. A bearing assembly for a cone crusher comprising:
an inner slide bearing having an inner slide bearing upper end and an inner slide bearing lower end;
an eccentric sleeve; and
an outer slide bearing arranged for supporting a lower portion of a crushing head shaft, the outer slide bearing having an outer slide bearing upper end and an outer slide bearing lower end wherein the inner slide bearing has an inner diameter (D1) and an axial height (H1) being defined from the inner slide bearing upper end to the inner slide bearing lower end, the outer slide bearing having an inner diameter (D2) and an axial height (H2) being defined from the outer slide bearing upper end to the outer slide bearing lower end, and wherein a ratio of the inner slide bearing axial height to the inner slide bearing inner diameter (H1/D1) is in a range of 0.95 to 1.20, and wherein a ratio of the outer slide bearing axial height to the outer slide bearing inner diameter (H2/D2) is in a range of 0.50 to 0.70.
