Strongest Sealing Solution in the Industry

The MECH-TC sealing system, exclusive to the Nuhn Header Series, utilizes a tungsten carbide mechanical seal to effectively protect the drive line and bearings. Tungsten carbide is extremely hard and wear resistant, which results in extended seal life in the harshest environments. The sealing system has been designed to withstand sand and other abrasive compounds. The MECH-TC system is designed to withstand tremendous load with three bearings, 2 tapered bearings and one needle bearing. The system is encased in an oil bath for ease of maintenance.
