A high-performance COMBI seal developed to control dust-induced leakage in underground mining gearboxes and comparable agricultural drive systems. The reinforced case and multi-lip design help retain gear oil, exclude fine mineral dust, protect shaft surfaces, and support stable gearbox operation in enclosed, abrasive environments.
This reinforced COMBI radial shaft seal provides reliable oil retention and contamination exclusion for gearbox shafts exposed to coal dust, rock powder, mud, and grit. Its rigid case supports secure installation, while the primary oil lip and auxiliary dust lips help reduce leakage and internal contamination. Custom dimensions, materials, and hardness selections are available for demanding applications.
