NTN 4T-JM205149 is a tapered roller bearing cone (inner ring with tapered rollers) for a single-row tapered roller bearing assembly. This cone must be paired with the correct matching cup (outer ring) to form a complete bearing. Tapered roller bearings are designed to carry combined radial loads and axial loads (in one direction). Because cone and cup are separable, installation is easier and axial end play/preload can be adjusted during assembly. For best performance, use a matching cup from the same manufacturer and replace cone and cup together when servicing.
