Lippert 122089 -- L44649 Tapered Roller Bearing Cone for Trailer Axle Hubs
A direct-replacement bearing cone machined to the industry-standard L44649 spec. Used in both inner and outer hub positions on Lippert-equipped trailers and RVs -- one of the most common trailer bearings in service today.
The Lippert 122089 is a genuine replacement L44649 tapered roller bearing cone engineered for trailer axle hub service. Whether you are repacking bearings on a routine maintenance schedule or replacing a worn set, this cone matches the geometry, load rating, and tolerance of the original equipment bearing used across a wide range of Lippert axle applications.
The L44649 is one of the most widely used trailer bearing sizes in North America. It is fitted as both the inner and outer bearing cone on many common hub configurations, which simplifies stocking -- one part number covers both positions in those setups. Always verify your specific hub configuration before ordering.
This cone is designed to mate with the L44610 bearing cup (race). If you are servicing a hub, replace the race at the same time as the cone for proper seating and maximum bearing life.
L44649 is a universally recognized bearing designation -- cross-references across major bearing brands including Timken, SKF, and National.
Depending on hub configuration, this cone serves both the inner and outer bearing positions -- reducing the part numbers needed for a full hub rebuild.
Always pair this cone with the correct L44610 cup/race. Mixing mismatched bearing families causes accelerated wear and potential hub failure.
Sourced as a genuine Lippert replacement (p/n 122089, vendor ref 62-0854) for use on Lippert-branded trailer axle assemblies.
A complete hub service on most trailer axles will require:
The L44649 bearing has a bore (inner diameter) of approximately 1.0625 inches (1-1/16 in) and an outer diameter of approximately 1.980 inches. Before ordering, confirm these dimensions match your existing bearing and hub. Trailer axle sizes vary -- do not assume fitment based on brand alone. Verify the bearing designation stamped or printed on your existing cone.
