Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 37 mm ID, 52 mm OD, 8 mm Thick 40411287

Freudenberg Sealing Technologies Simrit 40411287 rotary shaft seal is engineered to deliver superior sealing performance using 72 nitrile butadiene rubber (NBR) 902 elastomer for high durability and chemical resistance. It features a robust design with a 37 mm inside diameter, 52 mm outside diameter, and 8 mm thickness, tailored for rotary shaft applications.

This seal employs a spring-loaded sealing lip that provides excellent wear resistance and friction reduction when exposed to mineral and synthetic oils and greases. Its construction allows for effective sealing under pressures up to 0.5 bar and accommodates bidirectional rotating shafts with speeds up to 40 m/s, making it suitable for diverse industrial settings including aerospace, railway transport, automotive assemblies, power transmission, machine tooling, fluid handling systems, production lines, energy, and power generation sectors.

The seal's precise dimensions conform to shaft tolerance ISO h11 and housing bore tolerance H8 standards, ensuring a reliable and secure fit that reduces downtime and maintenance costs by prolonging seal lifespan and minimizing power loss.

As a replacement for R21 seals and occasionally R4, it supports applications ranging from axles and power tools to industrial gearboxes, motors, and pumps. The product's material composition and engineering confer 80% less friction torque and 50% lower specific heat generation compared to conventional seals, thereby improving efficiency and operational stability.

The seal leverages nitrile butadiene rubber elastomer for chemical compatibility and durability. Spring-loaded sealing lip enhances sealing efficiency and lifespan. Suitable for high-speed bidirectional rotary shafts up to 40 m/s.

Pressure stable up to 0.5 bar for various industrial applications. Compliance with ISO h11 shaft tolerance and H8 housing bore tolerance. Compatible with mineral and synthetic oils and greases to suit diverse environments.

Reduces friction and heat generation to lower operating costs. Versatile application across aerospace, automotive, industrial machinery, and energy sectors.

Manufactured in the Czech Republic, this Freudenberg Sealing Technologies Simrit seal meets rigorous quality and performance standards. It is an essential component for maintaining equipment uptime and efficiency in demanding industrial and commercial operations.
