Split bearing arrangement and a method of manufacturing a split bearing arrangement

A split bearing arrangement for reciprocating engines, the split bearing arrangement comprising:

• a bedplate section and a block section made of materials differing in hardness;
• the bedplate section, which includes at least a bedplate section clamping surface made of an iron material, being adapted to be clampable against the block section, the bedplate section having at least one positioning protrusion located on the bedplate section clamping surface, the at least one positioning protrusion having two longitudinal concave surfaces, two transverse concave surfaces and a substantially flat upper surface;
• the block section being made of a material having a hardness which is less than the hardness of the iron material of the bedplate section clamping surface, and the block section being adapted to be clampable and forcibly pressed against the bedplate section, wherein the block section includes a block section clamping surface in which at least one positioning groove is formable when the bedplate section is first pressed into the block section, the block section further having at least one material groove located in the block section clamping surface, the at least one material groove being adapted to receive material displaced from the block section when the at least one positioning protrusion of the bedplate section is forcibly pressed into the block section, and the at least one material groove being configured to be connected to the at least one positioning groove upon formation of the at least one positioning groove;
• wherein the bedplate section is configured to form the at least one positioning groove such that the at least one positioning groove is adapted to receive the at least one positioning protrusion after the first pressing.
