Product Description

The 4T-66225 NTN is a removable cone designed for a single-row tapered roller bearing. It comprises the inner ring and rollers, working in combination with a separate cup to form a complete bearing. The conical raceways and tapered rollers enable the bearing to handle radial and axial forces in one direction. Its design prevents sliding movements between the raceways and rollers, reducing component wear. Proper bearing operation requires a minimum load, and the separate cone and cup make for easy mounting and adjustment of axial clearance. For reliable operation, it is recommended to replace both cone and cup together and use components from the same manufacturer to avoid potential bearing problems resulting from differences in internal bearing profiles, material, and tolerances. Always pair the 4T-66225 NTN with a matching cup from the same manufacturer.
