This is an aftermarket replacement radial shaft seal, designed to be compatible with the specifications of Corteco part number 82017541NO. As a non-original equipment manufacturer (non-OEM) alternative, this seal provides a reliable and cost-effective solution for various industrial and agricultural machinery applications. It features precise dimensions of 105mm inner diameter, 130mm outer diameter, and a 12mm width, ensuring a proper fit for rotating shafts where effective sealing is critical. Constructed from high-performance PTFE (Polytetrafluoroethylene), often indicated by 'TFE' in the part name, this seal offers superior characteristics compared to traditional elastomer seals. PTFE is highly valued for its exceptional chemical resistance, very low friction coefficient, and ability to withstand a wide range of operating temperatures, from extreme cold to high heat. These properties make it particularly suitable for demanding environments where aggressive media or high shaft speeds are present, contributing to extended seal life and reduced maintenance requirements. The primary function of this aftermarket oil seal is to prevent the leakage of lubricants, hydraulic fluids, or other operational media from machinery components, while simultaneously protecting internal parts from contamination by dirt, dust, and moisture. By maintaining sealing integrity, this compatible replacement part helps ensure the efficient and reliable operation of engines, transmissions, gearboxes, and other critical mechanical systems, safeguarding machinery performance and longevity.
