摘要

System for balancing a roller (1) in a fiber web machine by moving its center of gravity (50) relative to its rotational axis (40) comprises balancing elements (10, 20) that are mounted on one or both ends of the roller so that they can be rotated about the rotational axis of the roller and have centers of gravity (11, 21) that can be displaced radially.
