Match a cone to the cup you already have
A cone is the inner ring with its rollers and cage; on its own it does nothing until it is paired with the correct cup. Stock runs from small metric 30200-series parts up to large inch cones near 3-3/4 in bore, with Timken and NSK numbers when available and some cone-and-cup sets offered together. Cone and cup carry separate part numbers, so identify both before ordering rather than assuming the pair. If the stamping has polished away, bore diameter and cone width narrow it down fast, and we can confirm the mate from the housing or hub number. Need the outer race by itself? Those are listed as tapered roller cups.
Our team can locate, cross-reference, and source all parts.
