Abstract
A mass balancing unit having a hollow balancing shaft, at least one balancing weight which is provided on the balancing shaft and at least one roller bearing which has an outer bearing ring and a plurality of roller members. A longitudinal portion of the balancing shaft forms an inner bearing ring, the roller members being received between the outer bearing ring and the longitudinal portion of the balancing shaft. Adjacent to the longitudinal portion, the balancing shaft has at least one recess in order to reduce the rigidity of the longitudinal portion of the balancing shaft in a radial direction.
