A Timken 67920CD tapered roller bearing double cup — one outer race carrying two tapered raceways, ground with oil holes and a circumferential lubrication groove. Double cup only. It takes two cones; the matching cone is the Timken 67985, used in pairs.
The D suffix on a Timken cup number marks a double cup: a single ring with two raceways instead of one. 67920 is the base cup number and the C denotes the lubrication provision in the outer race. Written as 67985/67920CD, the number describes a TDO assembly — Tapered Double Outer — two single-row cone assemblies seated back to back inside this one cup.
A TDO arrangement in a double cup gives thrust capacity in both directions and a wide effective bearing spread inside one housing bore, which is why it appears in mill roll necks, crane sheaves and large wheel hubs where a single row would need a second housing seat. Because both raceways are ground in one ring, the two rows stay square to each other without shimming the housing. The oil holes and groove let lubricant reach both raceways from a single housing port.

Series: 67900 inch tapered, TDO double cup

Parent assembly 67985/67920CD: 8.1250 × 11.1250 × 4.0000 in overall, 2 cones plus this cup
1 Pc — one double cup. The two cone assemblies and any spacer are separate components.
67920CD is the Timken double-cup number and carries unchanged across the inch tapered interchange. The 67920 without the D is a single cup with one raceway and a different width — a related size, not a substitute. Cone 67982 also runs against this double cup as 67982/67920CD; it differs in bore from the 67985, so the two assemblies are related sizes rather than equivalents.
