A bearing assembly for a cone crusher includes an inner slide bearing, an eccentric sleeve and an outer slide bearing arranged for supporting a lower portionof a crushing head shaft. The inner slide bearing has a diameter Dand an axial height Hbeing defined from the inner slide bearing upper end to the inner slide bearing lower end. The outer slide bearinghas a diameter Dand an axial height Hbeing defined from the outer slide bearing upper end to the outer slide bearing lower end. A ratio of the inner slide bearing axial height and its diameter H/Dis in the range of 0.95 to 1.20. A cone crusher including the bearing assembly is also provided.
