55176C/55443 Timken

The 55176C Timken 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, it forms a complete tapered roller bearing capable of absorbing radial and axial forces in one direction. Its design minimizes component wear by preventing sliding movements between the raceways and rollers, though a minimum load is necessary for proper operation. The separable cone and cup can be easily mounted and adjusted for axial clearance or preload during assembly. For reliable operation, it’s best to replace both cone and cup simultaneously and to use components from the same manufacturer to avoid potential bearing problems. Always pair the 55176C Timken with a matching cup from the same manufacturer.
