Needle roller+thrust ball NKX

The NKX series is a compact combination bearing consisting of radial needle rollers and unidirectional thrust balls. The inner ring design relies on quenched shaft necks as the inner raceway, with the needle rollers bearing heavy radial loads and the thrust balls bearing light to medium unidirectional axial loads. The overall radial cross-section is extremely compact, and the detachable structure is easy to install. It is suitable for compact shaft systems with radial heavy loads, unidirectional light axial positioning, and speed requirements. It is widely used in automotive transmissions, hydraulic pumps, motors, precision transmissions, automation equipment, and other scenarios, and is the mainstream choice for compact support under light axial loads.
