A Timken HM921348 single-row tapered roller bearing cone — the inner ring complete with its tapered rollers and cage. Bore 3-7/8 in.
HM921348 is an ANSI/ABMA inch tapered roller number. The HM prefix denotes a heavy inch section: a steeper raceway angle and a taller roller than the equivalent L or LM part in the same bore. The …348 ending marks the cone half; the cup half of the set is HM921310.
The steeper HM raceway angle trades a small loss of pure radial capacity for markedly higher single-direction thrust capacity, which is why the section appears in wheel ends and pinion positions rather than in plain radial shafting.

Cone only. The matching cup is the Timken HM921310. Sold as 1 Pc.
The cone presses onto the shaft journal against a square shoulder; the cup seats separately in the housing, and endplay or preload is set at assembly by shim or adjusting nut.
HM921348 is a standardised inch cone section carried under the same base number by Timken, Koyo, NTN and FAG. An HM cone of the same bore with a different base number is a related size, not an interchange, because the raceway angle differs.
