A bearing for an automotive engine includes a base having a first bearing segment formed therein, and a bearing cap removably mounted to the base, with the bearing cap including fastener towers in contact with the base. A second bearing segment extends between the fastener towers. A number of non-contact stiffening ribs extend parallel to the fastener towers. The stiffening ribs are attached to outboard portions of the fastener towers. The stiffening ribs cause the bearing cap to avoid excessive flexing and distortion, while at the same time avoiding fretting corrosion which would occur were the clamp loads of the cap to the base be reduced by materially increasing the size of the fastener towers. |
