FAGLM844010Tapered Roller Bearing Cup 11-5/8″ OD 1-3/8″ W Inch Series

Product Description

What this part is

An FAG LM844010 single-row tapered roller bearing cup — the outer race of an inch-series tapered roller bearing. Outside diameter 11-5/8 in, width 1-3/8 in.

Decoding the designation

LM844010 is an ANSI/ABMA inch tapered roller part number. The …010 ending marks the cup half of the pair; the cone half of the same set carries the number LM844049. The K- prefix seen on FAG cartons designates a cone, so it belongs to the mating number rather than to this part.

What these specs mean in practice

A tapered roller bearing carries combined radial and single-direction axial load through the raceway angle. Cup and cone are lapped as a matched pair at manufacture, so the raceway angle and roller path are common to the set number rather than to either half alone.

Interchange guidance

LM844010 is a standardised inch cup section, produced to the same envelope by Timken, FAG, Koyo and NTN under the same base number. A cup carrying a different base number is a related size, not an interchange.
