A direct-replacement idler hub for light trailer and RV axles rated at 2,200 lbs. The 814205 ships with everything you need to complete the bearing service in one box -- no hunting for separate inner and outer cones, cups, seal, or cotter pin.
The Lippert 814205 is a solid iron idler hub designed for trailer axles in the 2,200 lb. capacity range. It accepts 13 to 15 inch wheels on the standard 5 on 4.5 inch (5x114.3 mm) bolt pattern -- one of the most common patterns found on lightweight travel trailers, utility trailers, and boat trailers built on Lippert and comparable axle platforms.
Unlike bare-hub replacements that require sourcing bearings separately, this kit bundles the hub with a matched bearing cone set so you get the right inner and outer cones, cups, seal, and hardware in a single order. That matters when you are doing a roadside swap or a scheduled axle service and cannot afford a second trip to the parts counter.
Cast iron hub body resists the heat and shock loads generated during trailer braking and cornering, and holds up to repeated bearing service intervals without deformation at the bore.
One inner bearing cone, one outer bearing cone, matching inner and outer bearing cups, one double-lip grease seal, and one cotter pin are packed with the hub -- nothing extra to source.
Five lug studs on a 4.5 inch (114.3 mm) bolt circle. Matches factory wheel fitment on a wide range of lightweight RV and utility trailer axles without adapters or re-drilling.
Sized for 13 to 15 inch wheels. If you are upgrading from a 13 inch spare to a 15 inch road tire, or running the stock 14 inch, this hub clears the center bore properly across that range.
An idler hub (sometimes called a free-rolling hub) is used on non-braked trailer axle positions. It houses the wheel bearings and mounts directly to the spindle without the drum, magnet wiring, or brake flange hardware found on a brake hub assembly. Idler hubs are standard on the front position of tandem axle trailers where only the rear axle is braked, and on all positions of very light single-axle trailers below the brake threshold.
If your trailer has electric brakes on every axle position, you need a brake hub, not this part. See the Lippert brake hub listings for those applications.
The 814205 kit contains: (1) inner bearing cone, (1) outer bearing cone, (1) inner bearing cup, (1) outer bearing cup, (1) double-lip grease seal, and (1) cotter pin. Pack the cones with fresh wheel-bearing grease before assembly -- grease is not included.
This hub is engineered for axles rated at 2,200 lbs. It is a common replacement on Lippert-branded trailer axles and on OEM-equivalent axles built to the same spindle dimensions. The 1/2 inch lug studs and the 6.5 inch hub flange diameter are the key physical identifiers to verify against your existing hub before ordering.
This is a bolt-on replacement assuming the spindle and wheel are otherwise in serviceable condition. Remove the existing hub, clean the spindle, inspect for scoring or pitting, then install the new inner cup and cone, slide the hub onto the spindle, install the outer cup and cone, set bearing preload with the spindle nut, install the cotter pin through the castle nut and spindle slot, and fit the grease cap. Torque specifications follow the axle manufacturer's service manual for the spindle nut -- typically snug plus a quarter-turn back to the nearest cotter pin slot.
Re-pack wheel bearings with NLGI Grade 2 wheel-bearing grease at least once per season or every 10,000 to 12,000 miles, whichever comes first. Inspect the double-lip grease seal any time the hub is removed; replace the seal if the lip shows cuts, hardening, or deformation. A failed seal contaminates bearings quickly at highway speed.
This listing is for a non-braked idler hub. No brake drum, backing plate, magnets, or wiring are included or compatible. Do not use this hub on a braked axle position.
