Product Description
Product overview
High-polymer composite material wedge main wear plate is one of the spare parts of railway wagon. It’s installed onto the friction wedge of 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
Benefit from composition and manufacturing technique of High-polymer composite material which dedicated for railway freight car wear abrasion plate, friction coefficient of wear eliminator is stable, abrasion loss of noumenon is quite small. The friction plate is less affected by the external environment and temperature, does’t hurt the opposite during operation. It is a safe and reliable wear protector.

Product advantages
• CRCC certification approved
• Good of high temperature resistance,reach to 270℃
• Good of wear-resisting performance, noumenon abrasion loss as low as 1*10^(-8)
• Good of tensile strength, reach to 216MPa
• Stable of friction coefficient, 0.25
• Adhesive force between rub layer and strength layer reach to 63kN, enhanced service life
• More firmly connected between navel and strength layer, make umbilical shear force up to 88mPa
• Environmentally friendly, asbestos free
Friction plate including strength layer, navel, rub layer, below is a picture for reference.
