Abstract

The half bearing 31 supports a crank shaft of an internal combustion engine. The half bearing 31 includes a main cylindrical part 71 with a plurality of circumferential grooves 74 and crush reliefs 70 with a plurality of crush relief grooves 75. A groove width of the crush relief grooves 75 is the same as a groove width of the circumferential grooves 74. The plurality of crush relief grooves 75 are offset with respect to the plurality of circumferential grooves 74 in a width-wise direction of the half hearing by an amount at least exceeding 0 and less than the groove width. The half bearing may have transition regions between the main cylindrical part and the crush relief and may have an inwardly convex and/or outwardly concave portion. Two half bearings may be assembled into a cylindrical shape.
