The High Load Roller Bearing (HLRB) offers a reliable, zero-maintenance replacement for bearing sets currently deployed  on the helicopter hanger bay doors of U.S. Navy’s DDG-51Destroyer. The HLRB enhanced seal design prevents the ingress of liquids and particulates even under extreme environmental conditions and extreme off axis loading. Intended as a direct replacement for currently deployed helo-bay door bearings, the HLRB can be installed without the need for modification of helo bay doors or other ship structures. By utilizing advanced materials, coatings, and manufacturing processes in concert with a high load roller bearing design, the HLRB has provided U.S. Navy with a reliable solution for eliminating burdensome helo bay door  maintenance logistics and cost.
