Abstract
An assembly for connecting a sanding pad or the like to a driver having an axis of rotation, wherein the sanding pad is adapted to undergo free rotational movement about a second axis disposed parallel to the axis of rotation, as such sanding pad is caused to orbit about such axis of rotation. The assembly features a bearing assembly for supporting the sanding pad for rotation about the second axis, wherein an improved seal is provided to prevent ingress of abrasive materials into the bearing assembly during operation of the sanding pad, so as to prolong the useful life of the bearing assembly.
