Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal 55 mm ID 72 mm OD 8 mm 40413891

Freudenberg Sealing Technologies Simrit 40413891 rotary shaft seal manufactured from 72 Nitrile Butadiene Rubber 902 features a 55 mm inside diameter, 72 mm outside diameter, and 8 mm thickness. This high-performance seal is designed for demanding industrial applications such as aerospace, railway, power transmission, automotive, machine tools, fluid handling, production line, energy, and power generation.

The NBR 902 nitrile rubber elastomer outer casing, combined with a spring-loaded sealing lip, ensures compatibility with mineral and synthetic oils and greases, providing outstanding wear resistance. These seals significantly reduce friction and heat generation, lowering power loss and operational costs while extending the seal's working lifespan.

Freudenberg Simrit seals are ideal replacements for standard R21 seals and, in some applications, for R4 seals, offering improved sealing performance. Their design supports bidirectional rotating shafts at velocities up to 40 meters per second and is pressure stable up to 0.5 bar.

The product complies with ISO shaft tolerance h11 and housing bore tolerance H8 standards, enhancing fit and effectiveness in applications such as axles, industrial gearboxes, power tools, motors, and pumps.

Manufactured in the Czech Republic, these seals meet rigorous quality expectations and provide reliable performance in various industrial environments. This rotary shaft seal features an 8 mm thickness for effective sealing performance.
