Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 65 mm ID, 80 mm OD, 8 mm 40413812

Freudenberg Sealing Technologies Simrit 40413812 Rotary Shaft Seal, made from high-grade 72 Nitrile Butadiene Rubber 902, delivers exceptional wear resistance and sealing performance. With an inside diameter of 65 mm, outside diameter of 80 mm, and thickness of 8 mm, this seal is engineered for demanding rotary shaft sealing applications across various industrial sectors.

This seal features a spring-loaded sealing lip designed to accommodate mineral and synthetic oils and greases, providing a reliable seal against contaminants while minimizing friction and heat generation. Its design stability under pressures up to 0.5 bar and suitability for bidirectional shaft rotation speeds up to 40 meters per second make it ideal for challenging environments.

Thanks to compliance with ISO h11 shaft tolerance and H8 housing bore tolerance, this seal ensures a precise fit, reducing wear and extending service life. It offers an 80% reduction in friction torque and 50% less specific heat generation compared to traditional seals, leading to lower power loss and operational costs.

Suitable as a replacement for R21 and some R4 seals, this product finds application in aerospace, railway, automotive, production line machinery, fluid handling, and power generation equipment. The robust elastomeric casing provides durability in harsh industrial environments, reducing costly maintenance downtime.

Constructed from 72 Nitrile Butadiene Rubber 902 for durability and chemical resistance. Spring-loaded sealing lip adapts to shaft irregularities and lubricants. Pressure stability up to 0.5 bar allowing use in moderate pressure applications.

Bidirectional rotation capability up to 40 m/s suitable for high-speed shafts. Compliance with ISO h11 shaft and H8 housing tolerance standards for accuracy. Significant reduction in friction and heat generation to improve efficiency.

Extensively used in industries such as aerospace, automotive, power transmission, and machine tools. Manufactured in Czech Republic under strict quality control standards. Reliable sealing reduces equipment wear and prevents lubricant leakage.

Easy replacement for compatible seals such as R21, promoting operational continuity.
