Abstract

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 portion 5 of a crushing head shaft. The inner slide bearing has a 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 40 has a diameter D2 and an axial height H2 being defined from the outer slide bearing upper end to the outer slide bearing lower end 40b. A ratio of the inner slide bearing axial height and its diameter H1/D1 is in the range of 0.95 to 1.20. A cone crusher including the bearing assembly is also provided.
