Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal 8 mm ID x 22 mm OD x 7 mm 40413913

Freudenberg Sealing Technologies Simrit model 40413913 is a high-performance rotary shaft seal manufactured from 72 Nitrile Butadiene Rubber 902 with dimensions of 8 mm inside diameter, 22 mm outside diameter, and 7 mm thickness. This seal is designed to deliver exceptional wear resistance and reliability in a wide range of demanding industrial environments.

The seal's elastomer outer casing is crafted from NBR 902 nitrile rubber and features a spring loaded sealing lip, enabling compatibility with both mineral and synthetic oils and greases. These seals significantly reduce friction and heat generation during operation, resulting in lower power losses and increased working life. This reduces costly downtime due to seal wear and repairs.

Applications for this seal include aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy, and power generation sectors. With a shaft tolerance conforming to ISO h11 and housing bore tolerance of H8, the seal ensures precise mechanical fit and consistent sealing performance.

This model is pressure stable up to 0.5 bar and supports bidirectional rotating shafts at velocities up to 40 m/s. It is a suitable replacement for R21 seals and in some instances R4 seals, facilitating ease of integration in various machinery.

The seal casing material is 72 Nitrile Butadiene Rubber 902, offering high durability and chemical resistance. The seal thickness is precisely 7 mm for optimal sealing depth. The 8 mm inside diameter and 22 mm outside diameter are designed for standard shaft sizes.

Reduces friction torque by 80%, specific heat generation by 50%, and seal wear, improving operational efficiency. Ideal for use in industrial gearboxes, motors, pumps, power tools, and axle applications. Manufactured in the Czech Republic ensuring robust quality standards.
