This is a complete idler hub assembly for trailer axles rated at 3,500 lbs with a #84 spindle. It comes pre-greased, so it is ready to install. It has a 5 on 5-1/2-inch bolt pattern and 1/2-inch wheel studs.
The hub is precision-machined steel. It includes the bearings, races, grease seal, and cone wheel nuts. It works with both grease and E-Z Lube (zerk-lube) axle systems, and it suits hub replacement and axle repair on utility, cargo, boat, and equipment trailers.
