It has a compact structure and small volume, high rotation accuracy, and can bear a certain axial load while bearing a high radial load. And the product structure is diverse, adaptable and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system design very compact and smart.
