Abstract
Preferably, a tire inflation system includes a hub cap secured to a wheel attached to an axle of a vehicle, which provides a source of pressurized air. The tire inflation system preferably includes a rotary union assembly with a rotating portion and a non-rotating portion, the rotating portion attachable to the exterior of the hub cap for rotation with the hub cap. The non-rotating portion preferably includes a stationary shaft in fluid communication with the source of pressurized air, the stationary shaft defining an air passage therethrough which participates in conducting pressurized air to the tire. An end of the stationary shaft preferably provides a first bearing surface and a housing is rotatably mounted thereon for rotation with the hub cap. The rotating portion preferably includes a rotary member rotating with the housing, the rotary member defining a second bearing surface disposed in abutment with the first bearing surface.
