Product Overview: The NA 4914 Machined Ring Needle Roller Bearing
The NA 4914 is a precision-engineered needle roller bearing, distinguished by its compact design and exceptional load-carrying capabilities. With dimensions of 70x100x30mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NA Series of Machined Ring Bearings. It is designed to handle high radial loads within a minimal space, making it an ideal choice for applications where housing space is limited. The NA 4914 includes a solid inner ring, which allows it to be used on shafts that are not hardened and ground, providing greater design flexibility. Its robust construction ensures reliable performance and a long service life in demanding industrial environments.
As a leading supplier of needle roller bearings and mechanical parts, we guarantee that our NA 4914 bearings meet stringent industry standards for quality and dimensional accuracy. This bearing is essential for ensuring smooth and efficient operation in a wide array of machinery.
