Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal 10 mm ID 20 mm OD 6 mm 40411094

Freudenberg Sealing Technologies Simrit model 40411094 is a high-performance rotary shaft seal made with 72 nitrile butadiene rubber 902 elastomer. This seal measures 10 mm inside diameter (ID), 20 mm outside diameter (OD), and 6 mm thickness, designed to deliver exceptional wear resistance for demanding industrial uses.

The seal features a spring-loaded sealing lip construction that makes it suitable for mineral and synthetic oils and greases. It excels in reducing friction torque by approximately 80% and heat generation by about 50%, resulting in prolonged operational life and decreased downtime caused by seal maintenance or failure.

It is pressure stable up to 0.5 bar and supports bidirectional shafts rotating at velocities up to 40 m/s. The seal is suitable for applications in aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy, and power generation industries.

This model is an effective replacement for R21 and, in some cases, R4 seal types. The precise dimensions and material properties ensure compatibility with various industrial gearboxes, motors, pumps, and axles. Manufactured in the Czech Republic, it conforms to high standards of quality and reliability.
