摘要： There is provided a sliding bearing, which can continuously enhance conformability even when deformation by high oil film pressure in the vicinity of a central part of the sliding bearing occurs. The sliding bearing includes crownings which are each formed in an inclined shape toward an outer peripheral surface from an inner peripheral surface, at end parts in an axial direction, of an inner peripheral surface of a sliding bearing, so that even when the region in the vicinity of the central part of the sliding bearing 1 receives the oil film pressure and deforms in the recessed shape so as for both the end parts in the axial direction to locally contact a shaft, conformability can be enhanced not only at an early stage of use of the sliding bearing but also continuously by relief by the crownings.

摘要： A half plain bearing which can minimize lubricant leakage while retaining a crush relief function, comprising: grooved portions formed circumferentially on an inner surface of the half plain bearing; protrusions of the grooved portions in a secondary loaded portion being liable to running-in wear caused by contact with a shaft. Consequently, the protrusions undergo running-in wear through contact with the rotating shaft at an early stage. The worn protrusions serve the same purpose as crush reliefs, providing a crush relief function even though no crush relief is formed. This makes it possible to minimize lubricant leakage.
