It includes the pre-assembled hub with bearing cups, pre-greased bearings, a double-lip grease seal, a grease cap, and all necessary mounting hardware. The kit is designed for non-brake (idler) axles, allowing the wheels to spin freely. It is typically replaced when the hub is worn, damaged, or after bearing failure to restore proper wheel rotation and safety.
