A wheel for an inline skate type roller skate includes a wheel rim portion, a tread surface on the wheel rim portion and at least one ball bearing located entirely within the outer contour of the wheel. Disk-type seals mounted on the inner race of the ball bearing cover the axially outer surfaces of the bearing to protect the bearing against the entry of contaminants. The seals are also located entirely within the outer contour of the wheel.
