1. A bearing wheel, comprising:
- (a) a wheel centre,(b) bearings housed in the wheel centre and adapted to allow the wheel centre to spin about an axle around which the bearings are mounted,(c) an outer surface for contacting a frictional surface over which the wheel centre is to spin, and(d) air flow passageways formed through the wheel centre, the air flow passageways extending between opposite sides of the wheel centre to allow air flow therethrough to dissipate excess heat caused by friction while the wheel is moving on the frictional surface.

Abstract
A bearing wheel (50) has a wheel centre (53) and bearings (14, 16) housed in the wheel centre which are adapted to allow the wheel centre to spin about an axle (18) around which the bearings are mounted. There is an outer surface (20) for contacting a frictional surface over which the wheel centre is to spin. Air flow passageways (22) are formed through the wheel centre, and extend between opposite sides of the wheel centre to allow air flow therethrough to dissipate excess heat caused by friction while the wheel is moving on the frictional surface.

7. A bearing wheel, comprising:
-
(a) a wheel centre, (b) bearings housed in the wheel centre and adapted to allow the wheel centre to spin about an axle around which the bearings are mounted, and (c) an outer surface for contacting a frictional surface over which the wheel centre is to spin, the outer surface being provided by a cap that is secured around the wheel centre, wherein the wheel centre is made of a metal to prevent heat conduction and expansion of the wheel centre caused by frictional heat generated while the wheel is moving on the frictional surface. - View Dependent Claims (8, 9)
