Product Overview: The NA 6914 Needle Roller Bearing
The NA 6914 is a heavy-duty needle roller bearing with an inner ring, engineered to handle high radial loads within a compact design. With its precise dimensions of 70x100x54mm (Bore x Outer Diameter x Thickness), this bearing is a key component in applications where radial space is limited but significant load-carrying capacity is required. Part of the NA Series, it features a machined outer ring for enhanced rigidity and is designed for use on shafts that may not be hardened and ground, thanks to its included inner ring. This makes it an exceptionally versatile and robust solution for demanding industrial and automotive machinery.
As a leading supplier of Needle Roller Bearings, we ensure our NA 6914 meets stringent industry standards for performance and reliability. Its construction is ideal for supporting rotating shafts and minimizing friction under severe operating conditions.
