Product Description
Product Overview
Railway cast iron bogie friction wedges made from ADI (Austempered Ductile Iron) provide critical damping functionality for railway bogie systems. These components increase slewing damping between the bogie and car body, ensuring safe operation while restraining shaking and serpentine motion during transit.
Available in casting alloy steel, grey casting iron, and ADI materials, these wedges feature a specialized design with horizontal bottom surfaces, vertical front surfaces, and angled back surfaces to effectively dampen relative movement between bolster and side frame components in railroad car trucks.
