NA 4902 | XIC | Machined Type With IR | NA Series

NA 4902 The NA 4902 is a single‑row needle roller bearing with machined rings, flanges on the outer ring, and an inner ring — designed to deliver high radial load capacity while maintaining a low cross‑sectional height, making it ideal for assemblies where radial space is limited. Its compact form factor and dense arrangement of fine rollers ensure smooth, precise rotation, high stiffness, and reliable load distribution under continuous or heavy-duty conditions. This bearing is commonly used in gearboxes, pumps, alternators, and other mechanical systems needing durable performance and efficient operation.
