Key Features:

1. Cone component (removable inner assembly): Includes the inner ring + tapered rollers (not the cup/outer ring).
2. Pairs with a separate cup: Forms a complete single-row tapered roller bearing when matched with the correct cup (outer ring).
3. Handles combined loads: Designed to carry radial loads plus axial (thrust) loads in one direction.
4. Reduced wear design: Conical raceways + tapered rollers minimize sliding, helping reduce wear during operation.
5. Easy installation & adjustment: Cone and cup are separable for mounting, and end play/preload can be adjusted by axial positioning during assembly.
