Product Overview: The NKIA 5903 Combined Needle Roller Bearing
The NKIA 5903 is a high-precision combined bearing designed to accommodate both radial and axial loads within a very compact space. With principal dimensions of a 17mm bore diameter, 30mm outer diameter, and 20mm thickness, this component integrates a radial needle roller bearing with an angular contact ball bearing. This clever design makes it an ideal solution for applications where space is limited, but high load-carrying capacity and rigidity are essential. The needle roller section expertly handles high radial forces, while the angular contact ball bearing component is engineered to support axial loads in a single direction.
As a key part of our Needle Roller Bearings selection, the NKIA 5903 is manufactured to exacting standards, ensuring reliable performance in demanding industrial machinery. Its unique construction simplifies machine design by replacing two separate bearing arrangements with a single, compact unit. Explore our full range of Combined Needle Roller Bearings for innovative solutions to your most complex engineering challenges.
