As a cost-effective solution for lower sash weights, the new HS 250 compact bogie wheels, set apart by their lean, compact design, can carry 250 kg sash weight. Their innovative bearing technology, which takes, among other things, the weight distribution of energy-efficient triple glazing into account, provides enhanced smooth running.
