Product overview
Friction Railroad Wedge is one of the spare parts of railway wagon. The Friction Railroad Wedge is installed on wagon bogie anti-vibration device. Its function is to increase the slewing damping of the bogie and the car body, so that the car body can run safely and restrain the shaking and serpentine motion of the bogie and the car body.
With high temperature resistance and wear resisting performance, good tensile strength and stable friction coefficient, the friction railroad wedge has a long service life and good performance.
Material of friction wedges:
Casting Alloy Steel
Grey Casting Iron
Austempered Ductile Iron(ADI)
