Decoding the designation

13169 is the cone number in Timken’s 13000 inch series. The D suffix on a cone marks a DOUBLE CONE: one solid inner ring machined with two tapered raceways back to back, carrying two roller sets and two cages. Because the two raceways share a single ring, a double cone runs against two separate single cups rather than one. Searchable forms of the number are 13169D, 13169-D, 13169 D and 13169.

What these specs mean in practice

Bore: 1.6875 in, which is 1-11/16 in or 42.863 mm. Cone Width: 1.2500 in. The two raceways in one ring set the row spacing at the factory, so the axial position of the two rows relative to each other is fixed by the ring rather than by a spacer or by shimming at assembly. That makes a double cone the locating half of a TDI two-row arrangement, and it is the reason a TDI carries a single inner ring part number rather than two. Bearing Material: Case-Carburized Steel — a hard case over a tough core, which is what lets a tapered raceway take shock load without through-hardened brittleness. Harmonization Code: 8482.20.00.

Cone and cup mating

A D suffix on a cone means the part takes two single cups, one per raceway. This is the mirror of the cup convention, where a D or DC on a cup number marks a double cup that takes two cones.

Quantity and configuration

Unit Quantity: 1 Pc. Double cone only: one inner ring carrying both tapered raceways, with both roller sets and both pressed steel cages.

Interchange guidance

The plain 13169 raceway geometry also appears on single cones in the 13000 series, but a single cone gives one raceway on one ring and cannot substitute for the fixed two-row spacing this double cone provides. Two single cones plus a spacer is a different arrangement with a different assembled width.
