The tapered cone design allows the bearing to support combined radial and axial loads, providing smooth rotation and reduced friction. The cone assembly consists of the inner ring, tapered rollers, and cage, and is designed to be mounted in opposing pairs on a shaft. The matching cup (race) for this cone is part number LM29710.
