NKS series

The NKS series is a single row heavy series needle roller bearing without an inner ring and a dual gear edge solid ring. It consists of a dual gear edge solid outer ring and a needle roller cage assembly. It has no inner ring and relies on a shaft quenched and finely ground surface as a raceway, with a compact radial section and stronger load-bearing capacity. It is suitable for industrial scenarios such as low-speed heavy loads, limited radial space, and shafts that can be quenched and hardened raceways. It is commonly used for radial support in automotive transmissions, heavy-duty motors, construction machinery, mining machinery, printing machinery, and other equipment.
