A direct-replacement idler hub for light trailer axles up to 2,200 lbs, packaged with every bearing component you need to complete the job in one box. Built from solid iron for long-term durability on RV trailers, utility trailers, and boat trailers running 8- to 12-inch wheels on a 4 on 4-inch bolt circle.
Worn or damaged idler hubs are a common roadside failure on older RV trailers and small utility trailers. The Lippert 814206 lets you swap the entire hub assembly -- hub body, bearings, seal, and cotter pin -- without hunting down individual components separately. All mating surfaces are machined to accept the included bearing cups and cones, so fitment is guaranteed within the kit.
The solid iron hub body handles the daily stress of towing without the flex or cracking risk of lighter alloys at this axle weight class. Half-inch wheel studs match the stud size standard used across most light trailer axles in this bolt pattern family.
Cast solid iron hub body resists deformation and provides long service life under repeated load cycles on paved and unpaved roads.
Includes inner and outer bearing cones, inner and outer bearing cups, a double-lip grease seal, and a cotter pin -- no separate parts run required.
Four-lug, 4-inch bolt circle matches the most common wheel bolt pattern used on light RV and utility trailer axles rated at 2,200 lbs.
Accepts wheels from 8 to 12 inches in diameter, covering the full range of tire sizes typically paired with 2,200 lb trailer axles.
An idler hub (also called a free-spinning hub) rotates freely on the spindle using greased tapered roller bearings rather than being driven by a differential. On non-braking trailer axles, the idler hub carries the wheel load and transfers it to the spindle. Regular bearing inspection, repacking, and seal replacement are essential maintenance items -- this kit supports a complete service or full replacement in one purchase.
The 814206 kit includes all consumable components for a full hub installation:
Grease is not included. Use a high-quality NLGI #2 wheel bearing grease rated for trailer/automotive service. Pack both cones thoroughly before assembly.
The 814206 is designed for Lippert-supplied trailer axles rated at 2,200 lbs with the 4 on 4-inch bolt pattern. It is also compatible with many non-Lippert axles that share the same spindle dimensions, bearing sizes, and bolt circle. Common applications include:
