Product Description

The 4T-HM903245 NTN is a removable cone for a single-row tapered roller bearing, consisting of the inner ring and rollers. When paired with a separately available cup, these parts create a complete tapered roller bearing capable of absorbing radial and axial forces. The design prevents sliding movements between the raceways and rollers, minimizing component wear. Proper bearing operation requires a minimum load, and both the cone and cup are separable for easy mounting and adjustment of end play or preload. For reliable operation, it’s recommended to replace the cone and cup together and use components from the same manufacturer to prevent potential bearing problems.
