Product Description
Freudenberg Sealing Technologies Simrit model 40413751 is a high-quality rotary shaft seal made from 72 Nitrile Butadiene Rubber 902. Featuring an inside diameter of 60 mm, outside diameter of 80 mm, and thickness of 8 mm, this seal is engineered to deliver exceptional wear resistance and reliable sealing performance in demanding industrial applications.
The elastomer outer casing employs NBR 902 nitrile rubber combined with a spring-loaded sealing lip, making it highly compatible with both mineral and synthetic oils and greases. This design minimizes friction torque by approximately 80%, significantly reduces specific heat generation by 50%, and extends the working life of the seal, thus lowering operational downtime due to maintenance.
Commonly used across aerospace, railway, power transmission, automotive, machine tools, fluid handling, production line machinery, energy, and power generation sectors, this seal is a versatile and dependable choice for rotary shaft sealing needs. It can serve as a suitable replacement for R21 seals and in some cases R4 seals, subject to manufacturers' guidance.
Technical advantages include shaft tolerance conforming to ISO h11 standards and housing bore tolerance H8, ensuring precise fit and pressure stability up to 0.5 bar. The seal supports bidirectional rotating shafts at velocities reaching 40 meters per second. It offers superior resistance to wear, heat, and friction, enhancing overall equipment efficiency and durability.
Durable 72 Nitrile Butadiene Rubber 902 elastomer construction. Spring-loaded sealing lip for effective oil retention and contamination exclusion. Pressure stable and suitable for bidirectional rotation applications. ISO h11 shaft and H8 housing bore tolerance for accurate installation.
Wide industrial use in power tools, gearboxes, motors, pumps, and heavy machinery. Manufactured in Czech Republic to rigorous quality standards.
Set contains 1 rotary shaft seal with specified dimensions and material composition. Ideal for engineers and maintenance professionals demanding high performance sealing solutions with extended lifetime and reduced energy losses.
