Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 70mm ID 100mm OD 10mm 40412198

Freudenberg Sealing Technologies Simrit model 40412198 is an advanced rotary shaft seal constructed from 72 Nitrile Butadiene Rubber 902. It is designed with a 70 mm inside diameter, 100 mm outside diameter, and 10 mm thickness, making it ideal for various industrial sealing applications.

The seal features an elastomer outer casing made from durable NBR 902 nitrile rubber and includes a spring-loaded sealing lip. This construction ensures exceptional wear resistance and compatibility with mineral and synthetic oils and greases. These characteristics reduce friction and heat generation, minimizing energy losses and extending operational lifespan.

Designed for pressure stability up to 0.5 bar and capable of functioning on bidirectional rotating shafts with velocities up to 40 m/s, this seal is engineered for demanding industrial environments. Shaft tolerance meets ISO h11 standards, and housing bore tolerance is H8 for accurate fitment.

Widely used across aerospace, railway systems, power transmission, automotive machinery, machine tools, fluid handling systems, production lines, and energy/power generation sectors, this seal delivers reliable performance and reduced maintenance costs.

This product serves as a suitable replacement for R21 seals and in some applications R4 seals, enabling compatibility with existing equipment where applicable. This seal features a spring-loaded sealing lip suitable for rotary shaft applications reducing wear and friction effectively.

Made with NBR 902 nitrile rubber elastomer suitable for use with mineral and synthetic oils and greases. Provides significant improvements in heat and friction reduction contributing to longer seal life and reduced downtime.

Pressure stable up to 0.5 bar and designed for bidirectional rotating shafts with speeds up to 40 m/s. Commonly used in aerospace, railway, power transmission, automotive, machine tools, fluid handling, and energy sectors.

ISO h11 shaft tolerance and housing bore tolerance H8 ensure precise fitment. Manufactured in Czech Republic, ensuring high-quality standards in production.
