DX bearings are cutting-edge composite bearings designed to deliver exceptional performance in various applications. These bearings combine the advantages of different materials, offering a winning combination of strength, self-lubrication, and versatility. Whether you need bearings for heavy industrial machinery, automotive components, or marine equipment, DX bearings are engineered to excel. These bushes are marginally lubricated, they have pockets to retain grease or oil during operation.
