Product Overview: The NA 4902 Needle Roller Bearing
The NA 4902 is a high-performance machined ring needle roller bearing, complete with an inner ring, featuring dimensions of 15x28x13mm. As part of the versatile NA Series, this bearing is engineered to handle high radial loads within a very compact design. Its low cross-sectional height makes it an ideal solution for applications where radial space is limited. The inclusion of a precision-ground inner ring allows it to be used on shafts that have not been hardened and ground, offering greater design flexibility.
Manufactured to stringent industry standards, the NA 4902 ensures reliable and smooth operation in demanding environments. It is a key component in our extensive range of Needle Roller Bearings, trusted across various industries for its durability and precision.
