Abstract
A pair of skate bearing inserts are inserted into a hub of an in-line skate, roller skate, or skateboard. The bearing inserts have an integral cylindrical extension of a second axial end of an inner race thereby eliminating the need for a separate spacing member within a hub of a skate wheel. An inner groove along an inner circumference of the inner race engages with a bearing insert tool for quick removal and insertion of bearing inserts from skate wheels. A groove along a flange of a first axial end of the inner race allows for attachment of a reflective element to an outer surface of the skate wheel.
Claims9
A pair of skate bearing inserts positioned in abutting relationship in a hub of a skate wheel, each skate bearing insert comprising,
- a cylindrical inner race having a first axial end, a second axial end, an inner circumference, an outer circumference, an integral cylindrical extension of the second axial end projecting beyond a stop on an inner circumference of the hub to abut the integral cylindrical extension of the second axial end of the other bearing insert, and a central axial bore,
- a cylindrical outer race having a first axial end, a second axial end, an inner circumference, and an outer circumference, the cylindrical outer race rotatable around the cylindrical inner race, the first axial end of the outer race and the first axial end of the inner race defining an outer surface of the bearing insert,
- a ball bearing positioner inserted between the inner circumference of the outer race and the outer circumference of the inner race,
- a set of ball bearings inserted between the inner circumference of the outer race and the outer circumference of the inner race, the ball bearings held in place by the ball bearing positioner,
- means along the inner circumference of the inner race for cooperating with a bearing insert tool for removing and inserting the bearing insert from the hub of the skate wheel, and
- means for attaching a reflective element to the outer surface of the bearing insert.

- a cylindrical outer race having a first axial end, a second axial end, an inner circumference, and an outer circumference, the cylindrical outer race rotatable around the cylindrical inner race, the first axial end of the outer race and the first axial end of the inner race defining an outer surface of the bearing insert,
- a ball bearing positioner inserted between the inner circumference of the outer race and the outer circumference of the inner race,
- a set of ball bearings inserted between the inner circumference of the outer race and the outer circumference of the inner race, the ball bearings held in place by the ball bearing positioner,
- an annular inner groove formed within the central axial bore along the inner circumference of the inner race for engagement with a bearing insert tool for removal and insertion of the bearing insert from the hub, and
- means for attaching a reflective element to the outer surface of the bearing insert.
