Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 22 mm ID, 47 mm OD, 7 mm 40413413

Freudenberg Sealing Technologies Simrit model 40413413 rotary shaft seal is manufactured using 72 Nitrile Butadiene Rubber 902 elastomer. It is engineered specifically for high performance in sealing rotating shafts across a wide range of industrial applications including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy, and power generation.

The seal features a durable elastomer outer casing reinforced with a spring loaded sealing lip which allows efficient sealing for mineral and synthetic oils and greases. Its design focuses on minimizing wear, heat, and friction generation thereby reducing power loss and maintenance costs while extending operational lifespan.

Key technical dimensions include an inside diameter (ID) of 22 mm, outside diameter (OD) of 47 mm, and a thickness of 7 mm. This seal type is pressure stable up to 0.5 bar and supports bidirectional rotation at shaft velocities up to 40 m/s. It offers significant reductions in friction torque by 80% and specific heat generation by 50%, enhancing overall equipment efficiency.

Typical uses include replacement for R21, and in some cases R4 seals, suitable for axles, industrial gearboxes, motors, pumps, and power tools. The seal complies with shaft tolerance ISO h11 and housing bore tolerance H8.

Manufactured in Czech Republic, this shaft seal assures high quality and reliability in demanding industrial environments. Constructed with 72 Nitrile Butadiene Rubber 902 for excellent wear resistance. Rotary shaft seal design delivers effective sealing for rotating shafts.
