This is a pre-greased idler hub kit for trailer axles rated to 2,000 lb with a 1-inch spindle. It uses L44643 bearings and a 4-on-4-inch bolt circle, and ships with the bearings, grease cap, seal and lug nuts already matched to the hub. The pre-greased, pre-assembled setup saves repacking and guesswork compared with buying bare hubs and bearings separately. It fits Dexter, Al-Ko, Lippert, Hayes, Rockwell and Quality axles but not UFP or some marine axles, so bearing numbers must match before ordering.
