Product Description

The 4T-397 NTN cone is for a single-row tapered roller bearing, comprising the inner ring and rollers. It can be paired with a separately available cup to form a complete bearing. This design allows the bearing to absorb radial and axial forces in one direction while minimizing component wear. The separable cone and cup can be easily mounted and adjusted for axial clearance or preload. For optimal operation, it’s recommended to replace both cone and cup from the same manufacturer to avoid potential bearing problems.
