Specialized friction discs (Part 6Y7922) engineered for deep mining operations. Features spark-suppression technology and rockburst reinforcement for continuous operation in confined, methane-rich environments below 1,000m depth.
Designed for potash, coal, and rare-earth mines, 6Y7922 friction discs prevent ignition risks while withstanding seismic shocks in continuous miners, longwall systems, and shuttle cars.
