Abstract: A glass workpiece processing apparatus, such as a glass washer, includes a frame, a pair of rails attached to and extending along the frame, a plurality of workpiece supporting rollers positioned along the pair of rails, and a pair of bearing stands rotatably supporting each roller. Each bearing stand includes a base removably attached to one rail, a bearing attached to said base which rotatably supports the roller, and a releasable bearing retaining member attaching the bearing to the base. The bearing retaining member may be a snap-on clip including locking projections engaging corresponding locking notches in the base. Alternatively, the retaining member may include a stop screw threaded through a portion of the base.
