A bearing for use with a snowmobile track is disclosed. The bearing includes an axle surrounded by a sleeve which is free to rotate when the snowmobile track is driven by the machine. 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.
