摘要： An eccentric disk grinder has a housing, a motor accommodated in the housing and having a shaft provided with an eccentric member, a first bearing supporting the shaft, a grinding disk eccentrically, circulatingly and rotatingly driven by the motor through the shaft, and a second bearing in which the grinding disk is rotatable relative to the shaft about an axis of the eccentric member. The second bearing includes at least one first bearing which takes up substantially radial forces and supports at least one of the shaft and the eccentric member at its end facing the grinding disk. The bearings also have at least another second bearing which takes up substantially axial forces and supports at least one of the shaft and the eccentric member at its side facing away from the grinding disk.
