Abstract
A coating applicator is disclosed which includes a rotary atomizer on a driven shaft. The shaft operates at high speeds. Coating material is supplied to the rotary atomizer. A pair of spaced bearings rotatably mount the shaft and a seal assembly is positioned between the rotary atomizer and the front bearing. The seal assembly includes a bearing cover having a cutting edge. A mating cap member surrounds the shaft and has a sealing shoulder which is engaged by the cutting edge. Exhaust air is used to cool the bearings, pressure the interior of the applicator and enhance the seal assembly.
