The rails of the suspension systems of the snowmobile ride on the rolling surface resulting in reduced friction. The bearing can be used in a clip on the track or can be included in the track itself. A lubricious coating is utilized to reduce friction between the axle and the sleeve or bushing rotating about the axle.
