A Tyson M919049 tapered roller bearing cone with a Tyson M919010D double cup — one outer ring carrying two tapered raceways. TDO configuration, 90.000 mm bore, 6.3750 in outside diameter.
M919049 is the cone number. The D suffix on M919010D marks a double cup: a single outer ring with two raceways instead of one. TDO is Tapered Double Outer, the arrangement in which two cone rows sit back to back inside that one cup. The M prefix identifies a metric-bore size carried in an inch-style tapered number series, which is why a 90.000 mm bore reads as 3.5433 in.
Two rows back to back in a double cup take thrust in both directions and set the load lines wide apart, giving stiff resistance to overturning moment across a short shaft length. Both raceways being ground into one ring keeps the rows square without housing shims and reduces the fit to a single press into the housing bore. The metric bore lets the unit drop onto a shaft turned to ISO tolerances while retaining the inch tapered raceway geometry.

Raceways in the cup ring: 2
Rows: 2, back to back
Series: M919000 tapered, TDO, metric bore
Rolling element: tapered roller, chrome alloy steel

Supplied as a Tyson M919049 cone with the M919010D double cup, as titled. A complete TDO assembly uses two cones, one double cup and, on most arrangements, a ground cone spacer.
M919010D and M919049 are industry numbers and read the same under other brands, Timken among them. The M919048 is a separate cone that also runs against the M919010D double cup; it differs in bore, so it is a related size within the same cup family rather than a substitute for an M919049. A single-cup M919010 without the D has one raceway and a different width.
