Needle roller+angular contact ball - NKIANKIB

NKIA/NKIB is a compact combination bearing consisting of radial needle rollers and angular contact balls. NKIA bears unidirectional axial loads, NKIB bears bidirectional axial loads, needle rollers bear heavy radial loads, and angular contact balls bear light axial loads (≤ 25% radial loads). The separated structure is easy to install and suitable for industrial scenarios with radial heavy loads and light axial positioning, compact space, and high-speed operation. It is widely used in automotive transmissions, motors, pumps, valves, precision machine tools, and other equipment.
