Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal, 70 mm ID, 85 mm OD, 8 mm 40412334

Freudenberg Sealing Technologies Simrit 40412334 rotary shaft seal is manufactured from advanced 72 Nitrile Butadiene Rubber 902 elastomer, engineered for demanding sealing applications. With a 70 mm inside diameter, 85 mm outside diameter, and 8 mm thickness, this seal provides reliable performance in a variety of industrial uses.

These high-performance Simmering shaft seals feature a spring-loaded sealing lip that enhances sealing effectiveness, delivering exceptional wear resistance under both mineral and synthetic oil lubricants. The elastomer outer casing is crafted to minimize friction and heat generation during operation.

The seal's dimensional tolerances conform to ISO h11 for the shaft and H8 for the housing bore, ensuring a precise, tight fit to prevent leaks and contamination. The product is pressure stable up to 0.5 bar and can handle bidirectional rotation velocities up to 40 meters per second, making it ideal for high-speed rotating shafts.

This model reduces friction torque by 80% and heat generation by 50%, offering extended seal life and reducing maintenance downtime and operating costs. Suitable applications include aerospace, railway systems, automotive engines, power transmission assemblies, machine tools, fluid handling systems, production lines, and energy generation equipment.

Manufactured in the Czech Republic, this rotary shaft seal is a durable and trusted component for industrial sealing needs, providing engineers and maintenance professionals with a valuable solution to maintain equipment performance and longevity.

Designed for use with mineral and synthetic oils and greases. Spring-loaded sealing lip improves efficiency and reduces wear. ISO h11 shaft tolerance and H8 housing bore tolerance ensure tight fit. Pressure stable up to 0.5 bar to withstand operational stresses.
