NAF (W) borderless type

The NAF (W) series is a needle roller bearing with an inner ring and no blocking edge. The inner ring has no axial blocking edge, and the outer ring is designed for adaptability. It is equipped with a cage and needle roller components, and can only withstand pure radial loads. The radial section is extremely compact, and it is suitable for industrial scenarios that require axial displacement and limited radial space. It is widely used for shaft support in textile machinery, conveying equipment, precision transmission, and automation equipment.
