Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 18 mm ID 30 mm OD 7 mm 40411224

Freudenberg Sealing Technologies Simrit 40411224 rotary shaft seal is expertly engineered with 72 Nitrile Butadiene Rubber 902 material, offering a reliable sealing solution with 18 mm inside diameter, 30 mm outside diameter, and 7 mm thickness. This high-performance oil seal provides exceptional wear resistance, making it ideal for industrial applications such as aerospace, railway, power transmission, automotive, machine tools, and fluid handling machinery.

The seal features a spring-loaded lip which ensures effective sealing against mineral and synthetic oils and greases. Its design reduces friction and heat generation substantially, resulting in lower power loss and longer service life, minimizing costly downtimes related to seal maintenance or replacement.

With pressure stability up to 0.5 bar and suitability for bidirectional rotating shafts at velocities up to 40 meters per second, this seal supports demanding industrial environments. The Freudenberg seal is a suitable replacement for R21 and, in some applications, R4 seals (refer to manufacturers datasheet).

Key benefits include reduced friction torque by 80%, 50% less specific heat generation, and enhanced heat and wear resistance. It supports a wide range of machinery components such as axles, power tools, industrial gearboxes, motors, and pumps.
