Detailed Introduction
Powder Metallurgy Brake Pads for 160 km/h EMU Trailer Bogies-Technical Specifications
1.Product Overview
These powder metallurgy(PM)brake pads are specifically designed for 160 km/h EMU trailer bogies,providing reliable braking performance for non-powered axles.They feature optimized friction materials and durable construction to ensure stable braking under frequent stop-and-go operations.
2.Key Features
?High Friction Stability–Maintainsμ=0.32–0.38 across speed ranges
?Enhanced Heat Dissipation–Withstands 600°C continuous braking
?Low Wear Rate–≤0.08 cm3/MJ(extends service life)
?Reduced Noise&Vibration–Optimized for urban/suburban rail operations
?Dovetail/Flat-Back Options–Compatible with standard brake calipers
