HM813843 Timken

The HM813843 Timken 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 (or outer ring), it forms a complete tapered roller bearing, capable of withstanding radial and axial forces in one direction. Its design minimizes sliding movements between the raceways and rollers to reduce wear, although a minimum load is necessary for optimal operation. The separable cone and cup can be easily mounted and adjusted for end play or preload during assembly. For reliable performance, it’s recommended to replace both cone and cup simultaneously, ensuring they are from the same manufacturer to avoid potential bearing problems caused by differences in internal profiles, material, and tolerances. Always pair the HM813843 Timken with a matching cup from the same manufacturer.
