LM104910
This is a tapered roller bearing cup (outer race) for a wheel end assembly on heavy-duty trucks and trailers. It pairs with a matching cone (inner bearing) to support the weight of the vehicle and allow the wheel hub to rotate smoothly around the axle spindle. You replace this part when servicing wheel bearings, or if you notice wear, pitting, heat discoloration, or growling noise from the wheel end. It’s a single separable component, so always inspect the mating cone at the same time.
The exact vehicle fitment depends on the axle and hub assembly. This cup is used across many Class 8 truck and trailer axles (e.g., Freightliner, International, Great Dane) where the specified outer wheel bearing set calls for a JLM104910 cup. Verify the cone number as well—common cones paired with this cup include JLM104948. The inventory lists LM104910 (no 'J'), which is the same part; the 'J' prefix is often dropped in listings.
