Keep your trailer rolling safely with this OEM-spec replacement inner bearing cone from Lippert. Designed specifically for 6,000 lb rated axle hubs, this cone is a direct drop-in replacement when servicing or rebuilding your trailer wheel ends. Always replace the bearing cone and race together for the longest service life and the safest results.
Bearing maintenance is one of the most critical -- and most overlooked -- aspects of trailer ownership. A worn or pitted bearing cone is responsible for a significant percentage of trailer wheel failures on the road. The Lippert 122091 gives you a factory-matched replacement that fits properly, seats correctly, and carries the load rating your axle was engineered for.
This is the inner bearing cone, which seats against the inner race inside the hub and carries the majority of the radial load on each wheel end. Because the cone and race wear together, Lippert and virtually every bearing manufacturer strongly recommend replacing both components at the same time. The matching inner bearing race (cup) is sold separately -- do not reuse a worn race with a new cone.
Engineered to Lippert's specifications for 6,000 lb axle hubs. No guesswork on fitment -- this is a verified direct replacement for the original inner bearing cone.
Manufacturer reference number 15123 and Keystone part number 601941 make it easy to confirm you have the correct bearing for your application.
Always pair a new cone with a new race. Mixing a new cone against a worn race accelerates wear and can lead to premature failure -- especially under load at highway speeds.
Backed by a limited 1-year manufacturer warranty from Lippert, one of the largest and most established RV chassis and axle suppliers in North America.
The inner bearing cone (this part) sits toward the inside of the hub, closest to the axle flange. It is larger than the outer bearing cone and handles the primary radial load. Make sure you are ordering the correct position -- inner and outer cones are not interchangeable on the same hub.
