Timken HM 218248 is a tapered roller bearing cone—the cone half of a two-piece bearing designed to pair with its matching cup in a full Timken tapered roller bearing assembly. Sold as cone only, the part is identified by the HM 218248 designation and provides the precise race geometry required for proper fit in HM-series applications. This cone component is used wherever a Timken taper roller bearing cone is specified, relying on compatible Timken cups to complete the bearing for rotary motion with controlled radial and axial loads.
