Main Description

The Rotary Shaft Seal CORTECO 12007327 PU NA300 60x70x12 is a high-performance industrial seal developed for applications where standard rubber gaskets or elastomer-based shaft seals are not sufficient. The use of PU NA300 polyurethane provides exceptional resistance to abrasion, deformation, and dynamic mechanical stress, making this seal suitable for continuous operation in harsh working conditions.

Polyurethane material ensures excellent resistance to hydraulic oils, lubricants, and mechanical fatigue, which is critical in agricultural and industrial machinery operating under heavy loads. The precisely engineered sealing lip maintains stable contact with the shaft surface, effectively preventing oil leakage while minimizing wear of both the seal and the mating shaft.

With dimensions of 60x70x12, this sealing ring is optimized for use in hydraulic drives, power transmission systems, and rotating components where reliability and long service life are essential. The seal integrates easily into standard housings and can be installed using conventional mounting tools, provided correct axial alignment is maintained.

The shaft seal corresponds to Claas OEM reference 02120420 and EAN 3358960223791, making it a reliable replacement component for professional service operations, spare parts distribution, and B2B supply chains. Due to its consistent quality and durability, it is widely selected by maintenance departments, agricultural machinery workshops, and industrial customers seeking robust hydraulic sealing solutions.
