Product Description

The 28921B Timken is an outer ring cup designed for a single-row tapered roller bearing. When combined with a separately available cone, it forms a complete tapered roller bearing with conical raceways and roller elements, allowing it to absorb radial and axial forces in one direction. The external flange on the cup facilitates easy axial placement in a housing, resulting in a more compact and simple bearing design while enabling easier alignment of seals. The separable cup and cone allow for easy mounting and adjustment of end play or preload during assembly. For optimal performance, it is recommended to replace both the cup and cone simultaneously from the same manufacturer to prevent potential bearing problems.
