Product Description

The 39521UR Koyo (JTEKT) is an outer ring designed for use with a separate cone to create a complete tapered roller bearing. Its conical raceways and roller elements allow it to handle both radial and axial forces, and its design minimizes wear and allows for easy assembly. For best results, it’s recommended to replace both the cone and cup at the same time and to use components from the same manufacturer.
