Antal Ball Bearing Genoa cars are fitted with 2 Torlon ball circuits (lower) and 2 Delrin ball circuits (upper), providing higher efficiency and smoother running. The cars are fitted with side windows for easy maintenance and ball bearing cleaning or replacement. The ball bearing Genoa cars have better load resistance to vertical, horizontal and torsional loads, giving a higher safety margin as the car will remain on the track after ball bearing failure (overload).
