1.Product Introduction:
NKX bearing, which is combined needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust ball bearing. NKX bearing features compact structure, small size and high rotating accuracy and bearing certain axial load while holding very high radial load. NKX bearing has multiple structure styles, broad adaptability and easy installation. Further more it can be inlayed with our IR standard ring. It is widely used in machine tool, metallurgical, textile and printing machinery. NKX bearing can make the design of machine system highly compact and nimble.
