PCT No. PCT/SE82/00323 Sec. 371 Date Jun. 2, 1983 Sec. 102(e) Date Jun. 2, 1983 PCT Filed Oct. 7, 1982 PCT Pub. No. WO83/01283 PCT Pub. Date Apr. 14, 1983.A crankshaft for combustion engines has a number of components joined to each other. Each component comprises a counterweight, a portion of a main bearing journal, and a portion of a crank bearing journal. Adjacent components are so arranged that their crank bearing journal portions are connected to each other to form a complete crank bearing journal, and their main bearing journal portions are secured to each other to form a complete main bearing journal. One of each pair of portions is longer than the other; and oil ducts extend through cavities in the components but do not communicate with those cavities. Instead, the ends of the ducts open through the journal bearing surfaces, and specifically through the longer of the two journal portions so that the opening of the ducts can be central of the journal and still not interfere with the joint between the components.
