A device for protecting the bearings of the in-line roller skates provided in the form of an axle aperture plug. Each axle aperture plug comprises a spacer portion, a transverse axle bore and a protective flange. The spacer portion has an inner bearing surface for engaging the inner race and spacing the outer race from the frame of the in-line skate. The transverse axle bore through the spacer portion permits passage of an axle along the central axis of rotation of the wheel. The transverse axle bore has a cross-sectional diameter allowing the entire length of the axle to be slidably insertable through the transverse axle bore. The protective flange is disposed about the spacer portion and has a surface which extends symmetrically away from the transverse axle bore and terminates in an outer bearing surface adapted for proximate positioning with respect to the outer race of the wheel bearing when the aperture plug is installed in the in-line roller skate. In this way, the wheel bearing is protected from exposure to particulate contaminants during use of the in-line roller skate by the skater.

An axle aperture plug for installation in an in-line roller skate usable by a skater on a riding surface, said in-line roller skate including at least three wheels, at least three wheel axles, a frame, and clamping means, each said wheel having a central axis of rotation, each said wheel axle having a predetermined length and being positional on said central axis of rotation, said frame carrying said wheel axles so as to rotatably mount said plurality of wheels on said frame and to substantially center all said wheels substantially perpendicular to a common plane, each said wheel including a tire member, a hub, and bearing means including an inner and outer race, carried by said hub and supported on one of said wheel axles, said tire member being supported on said hub, and said frame including a plurality of axle apertures being arranged in pairs of axle apertures, with the axle apertures of each said pair confronting each other and being positioned on one said wheel axis of rotation, and said clamping means being disposed on each said wheel axle for attaching said wheel axle to said frame and clamping a pair of said axle apertures plugs between said inner race and said frame, each said axle aperture plug comprising: a spacer portion having an inner bearing surface for engaging said inner race and spacing said outer race from said frame; a transverse axle bore through said spacer portion for passage of one said axle along one said central axis of rotation of said wheel, said transverse axle bore having a cross-sectional diameter allowing the entire length of said axle to be slidably insertable through said transverse axle bore; and a protective flange disposed about said spacer portion and having a surface symmetrically extending away from said transverse axle bore and terminating in an outer bearing surface adapted for proximate positioning with respect to said outer race when said aperture plug is installed in said in-line roller skate, so that said bearing means is protected from exposure to particulate contaminants during use of said in-line roller skate by said skater, wherein said outer bearing surface is disposed in a first vertical plane and said inner bearing surface is disposed in a second vertical plane, and said first vertical plane is separated from said second vertical plane.
