This difference produces
the vertical vibration.
The conventional balancing
The vibration of finishing sander is mostly produced by the orbital action of base. In order to suppress it, a balancer
is so equipped at the axis, that its center of gravity comes to the opposite side of the center of gravity of base.
In the conventional balancing system, it was difficult to suppress the vertical vibration. Because, the both centers
of gravity are not on the same level as illustrated in Fig. A.
In case of BO4900V, BO4900 and BO4901, even the vertical vibration is suppressed by the new formed balancer,
by bringing both centers of gravity to the same level as illustrated in Fig. B.
