Vibrational linear conveyor for conveying workpieces and powdery or granular materials with a useful mass and a counter mass, which are equal in magnitude, are mounted separately at a vibrating system and, for conveying, can be brought into an opposite oscillating or vibrating movement over an electromagnetic exciter element comprising a magnet coil and a magnet armature, both of which are parts of the useful or counter mass. The workpieces or materials are transported by means of the oscillating or vibrating movement on a trough-like conveying element, which is part of the useful mass, along the conveying element, the useful and counter masses of the same magnitude lying essentially one above the other and being built up symmetrically on either side of a vertical central plane, in which the centers of mass of the useful and counter masses are resting on a common line of action. Various conveying elements are fastened interchangeably, an element-specific additional mass being provided, which is disposed at or mounted and designed at a conveying element or another part of the useful mass in such a manner, that the total weight of the useful mass as well as the position of the centers of the useful mass remained essentially the same, the total weight of the useful mass corresponding to that of the counter mass.
