A Timken 389AW/382 single-row tapered roller bearing, supplied as both halves together: the 389AW cone with its rollers and cage, and the 382 cup. Unit Quantity: 1 Set, one cone and one matching cup, which is one complete bearing.
389A — the cone. It fixes the bore, the cone width and the raceway angle. W is a Timken variant marking on that cone.
382 — the cup. It fixes the outside diameter and the matching outer raceway.
Timken writes a tapered roller bearing as cone number over cup number. Either half can be ordered on its own by its own number.
Bore Diameter: 2-1/8 in (2.1250 in, 53.98 mm). Outside Diameter: 3-7/8 in (3.8750 in). Number Of Rows: 1. Rolling Elements: Tapered Rollers. Series: 380 imperial tapered roller. Bearing Material: Case Carburized Steel. Harmonization Code: 8482.20.00.
Cone Part Number: 389AW. Cup Part Number: 382. The cone and cup are separable halves of one single-row bearing.
389A and 382 are industry-standard numbers carried by other tapered roller bearing makers. The 382A and 382S are different cups in the same family with their own widths, related sizes. A plain 389 without the A is an earlier design of the cone, a related part. Search forms: 389AW/382, 389AW-382, 389A/382, 389A, 389AW, 382.
