Powder Metallurgy Brake Pads for 160 km/h EMU Trailer Bogies

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
