This is a cone only: the tapered inner ring with its roller and cage assembly. The cup, the separate outer ring the rollers actually run against, is not included. A tapered roller bearing is only a bearing when you have both halves. This part mounts on a shaft, not in a housing bore.
Buy it if your existing cup is installed and in good condition and you need the rotating half. If you need a complete bearing, contact Central Surplus about the mating cup before you order.
A New Old Stock inch-series Timken tapered roller cone marked 5784T. The ring is stamped 5784T / TIMKEN / MADE IN USA. It arrives in its original carton, printed THE TIMKEN ROLLER BEARING COMPANY, CANTON · OHIO · U.S.A. and labelled 5784-T CONE / MARCA REGISTRADA — a corporate name Timken retired in 1970, which dates this as genuinely old stock rather than recent production in a vintage box.
The bore is plain straight cylindrical, with no taper and no keyway. Single row, cone only.
Bearings outlive catalogues. A machine built in the 1950s or 1960s may still be running, and the cone that fits it may have been dropped from the current range decades ago even though the machine has not changed. Obsolete inch-series numbers like this one are exactly what maintenance departments cannot buy new, which is why New Old Stock in the original carton has real value: it is dimensionally the part the machine was designed around, not a modern approximation that requires reworking a shaft.
Written variously as 5784T, 5784-T, 5784 T and 5784. Carton designation is 5784-T CONE. Related current-catalogue numbers in the adjacent range are 5578, 5584 and 575, none of which are stated interchanges — they are listed here only as search context. An industry-quoted mating cup of 5735 circulates; confirm before relying on it.
