Bishop-Wisecarver Corp., Pittsburg, Calif., manufacturer of guided motion technology including the patented DualVee guide wheel, announced it has been awarded a third U.S. patent for a washdown wheel with a new kind of bearing. The bearing incorporates the company's patented inner seal and outer shield design. This design lets the out shield act as a momentary seal while pressure from high velocity fluid causes the shield to deflect and conform to the wheel’s metallic surface. When the pressure is removed, the shield returns to its normal position, letting any liquid and debris that entered between the shield and seal drain out or be spun out by centrifugal force.
