Wheel assembly apparatus

A wheel assembly apparatus comprising:

• a wheel;
• a wheel hub positionable coaxially within the wheel, the wheel hub providing laterally opposing first and second sidewalls that are concave or otherwise inwardly tapered, such that a hub width of the wheel hub is less than a wheel width of the wheel;
• a first bearing and a laterally opposed second bearing each positionable coaxially within the wheel hub, an inwardly facing medial surface of the first bearing laterally spaced apart from an opposing inwardly facing medial surface of the second bearing so as to form a bearing gap therebetween;
• a first outer spacer positionable in contact with an outwardly facing lateral surface of the first bearing;
• and
• a second outer spacer positionable in contact with an outwardly facing lateral surface of the second bearing;
• whereby, an axle is capable of extending coaxially through each of the first outer spacer, first bearing, second bearing, second outer spacer, wheel hub and wheel, thereby enabling the wheel to rotate about the axle.

A wheel assembly apparatus for use in a wheel hub of a wheel, the apparatus comprising:

• a first bearing and a laterally opposed second bearing each positionable coaxially within the wheel hub, an inwardly facing medial surface of the first bearing laterally spaced apart from an opposing inwardly facing medial surface of the second bearing so as to form a bearing gap therebetween;
• a first outer spacer positionable in contact with an outwardly facing lateral surface of the first bearing;
• a second outer spacer positionable in contact with an outwardly facing lateral surface of the second bearing;
• and
• each of the first outer spacer and second outer spacer positioned substantially external to the wheel hub;
• whereby, an axle is capable of extending coaxially through each of the first outer spacer, first bearing, second bearing, second outer spacer, wheel hub and wheel, thereby enabling the wheel to rotate about the axle.
