LIEBHERR WET BRAKE PISTON SEAL RING

Ask about product

Dynamic hydraulic seal ring for the brake-actuating piston in Liebherr wheeled excavator final-drive wet-brake assemblies. Separates brake-circuit pressure from the oil-bath environment inside the planetary reduction gearbox, preventing fluid cross-contamination and maintaining brake performance. OEM profile engineered for precise fit, high-pressure extrusion resistance, and extended service life under continuous braking cycles.
