Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal, 25 mm ID, 42 mm OD, 7 mm 40413231

Freudenberg Sealing Technologies Simrit 40413231 rotary shaft seal is manufactured with 72 Nitrile Butadiene Rubber 902, featuring a 25 mm inside diameter, 42 mm outside diameter, and a 7 mm thickness. This high-performance shaft seal delivers exceptional wear resistance and durability for demanding industrial applications.

The seal utilizes an elastomer outer casing made from NBR 902 nitrile rubber combined with a spring-loaded sealing lip, providing compatibility with both mineral and synthetic oils and greases. It significantly improves seal wear characteristics while reducing heat and friction generation, resulting in lower power loss and longer service life.

Designed for bidirectional rotating shafts operating at velocities up to 40 m/s and pressure stability up to 0.5 bar, this seal ensures effective sealing performance across a wide range of industrial equipment including aerospace, railway, power transmission, automotive, machine tools, fluid handling systems, production lines, and energy generation equipment.

The seal's shaft tolerance complies with ISO h11 and housing bore tolerance with H8, ensuring precise fitting and function. It offers an 80% reduction in friction torque and 50% less heat generation compared to conventional seals, improving efficiency and reducing maintenance downtime.

Its robust construction and material composition make it ideal for applications involving axles, power tools, industrial gearboxes, motors, and pumps. Manufactured to high standards in the Czech Republic, this Freudenberg Sealing Technologies Simrit product comes from a reputable brand known for quality sealing solutions.
