Product Description
The 4T-3578 NTN is a removable cone for a single-row tapered roller bearing, consisting of the inner ring and rollers. When combined with a separately available cup, these parts form a complete tapered roller bearing that can absorb radial and axial forces. Its design minimizes component wear, requires a minimum load for proper operation, and allows for easy mounting and adjustment of axial clearance or preload. For reliable operation, it is best to replace both the cone and cup at the same time and to use components from the same manufacturer to prevent bearing problems caused by differences in internal profiles, material, and tolerances. Always pair the 4T-3578 NTN with a matching cup from the same manufacturer for optimal performance.
