The NKIA 5904 RICH is a combined angular contact ball and needle roller bearing (20x37x23 mm) for simultaneous heavy radial and high axial load support.
The NKIA 5904 RICH is a sophisticated combined bearing that integrates two distinct bearing types into a single, compact unit: a needle roller bearing and an angular contact ball bearing. Manufactured by RICH, this unit features precise metric dimensions of 20 x 37 x 23 mm.
This innovative design is engineered for applications that demand high radial and axial support within a minimal installation space. The needle roller section is highly effective at managing heavy radial loads while offering excellent radial rigidity. Concurrently, the angular contact ball section handles high axial loads acting in a single direction, ensuring accurate and stable shaft guidance. The presence of both polyamide and steel cages reflects the specialized requirements of the internal components for optimized longevity and rotational stability. The NKIA 5904 RICH is an ideal solution for machine tools, industrial pumps, and precision mechanical systems where space is limited but high multi-directional load capacity is essential.
