Abstract
A compensating shaft (1, 1a, 1b, 1c, 1d) for compensating mass forces and/or mass moments of a reciprocating piston internal combustion engine (13) is provided, with at least one bearing journal (2a, 2b, 2c, 2d), on whose outer casing surface (3a, 3b, 3c, 3d) the compensating shaft is supported in the radial direction in a housing support (10) of the reciprocating piston internal combustion engine, and with at least one unbalanced section (4) bordering the bearing journal in the axial direction. The outer casing surface of the bearing journal is formed on the side of the unbalanced section facing away from the unbalanced direction by a cylindrical section (5) of the bearing journal and by one or more axial projections (7a, 7b, 7c, 7d), wherein these axial projections extend like a collar from the cylindrical section while forming a radial undercut (6).
