Abstract

A ball bearing (110) which is dampened by a squeeze-film is disclosed. Pressurized oil is supplied through channels (117, 118, 116) to groove (115). By that way a squeeze-film is created between the inner surface of insert (113) and the outer race (110a) of ball bearing (110). The ball bearing (110) can be used as crankshaft bearing. The crankcase (2, 3) can be made of a light aluminium-alloy. At ambient temperature (25 degree Celsius) ball bearing (110) is press-fitted within crankcase (2, 3). At working temperature (120 degree Celsius) ball bearing (110) is clearance-fitted within crankcase (2, 3).
