Richmond gate track wheels, used on both automatic sliding gates (electric sliding gates) and manual sliding gates, are precision machined to ensure a smooth and consistent rolling action on the gate track. For the gate track to suit, see GTR010. Richmond gate track wheels are zinc plated to protect from rust. The double bearing design of our gate track wheels ensures a longer life and increases load capacity. The frame of these recessed gate track wheels is design to mount recessed into the bottom of the gate. For a track wheel design that bolts flat to the bottom of the gate, see our bottom mount track wheels.
