The tail wheel assembly can be on tricycle-type landing gear, as well as conventional gear with the tricycle gear being the most common. Tail wheels are designed to support a portion of the load requirements for the aircraft along with the main wheels, and are steerable on some aircraft. Wheels are made from either aluminum castings, magnesium castings, or aluminum forgings. The wheel is of the divided type, incorporating inner-wheel half and outer-wheel half, which are fastened together with tie bolts, washers, and nuts. The wheel rotates on two tapered roller bearings which seat in bearing cups, shrink fitted into the hubs. Molded grease seals provide protection and lubricant retention for the bearings. Hubcaps, when used, are secured to the outboard wheel half by a snap ring and screws.
