Product Overview: The NA 4913 Machined Ring Needle Roller Bearing
The NA 4913 is a high-precision needle roller bearing featuring a machined outer ring and an inner ring, with principal dimensions of 65x90x25mm. As a vital component in our NA Series, this bearing is designed to handle high radial loads within a very compact space. It is part of our extensive range of Machined Ring Bearings, which are known for their rigidity and high running accuracy. The inclusion of an inner ring makes the NA 4913 suitable for applications where the shaft cannot be hardened and ground as a raceway. This versatile bearing provides a reliable and space-saving solution for a wide variety of industrial and automotive applications.

Features of the NA 4913 Bearing
- High Radial Load Capacity: Its design with multiple small-diameter rollers provides a large contact area to support heavy radial loads.
- Compact and Space-Saving: Features a low cross-sectional height, making it ideal for applications with limited radial space.
- Includes Inner Ring: Comes complete with an inner ring, allowing for use on standard shafts without the need for special heat treatment or grinding.
- Machined Outer Ring: The solid, channel-shaped outer ring offers high rigidity and precision, ensuring stable performance under load.
- Cage-Guided Rollers: The needle rollers are precisely guided by a cage, which reduces friction, minimizes heat generation, and allows for higher operational speeds.
- Versatile Design: The inner ring can be omitted in applications where the shaft is suitably hardened and ground, providing design flexibility.
