Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 25 mm ID, 36 mm OD, 7 mm 40411184

Freudenberg Sealing Technologies Simrit 40411184 rotary shaft seal is engineered with 72 Nitrile Butadiene Rubber 902, providing excellent wear resistance and performance suitable for diverse industrial applications including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy sectors, and power generation equipment.

Featuring an elastomer outer casing made from NBR 902 nitrile rubber and a spring-loaded sealing lip, this seal functions efficiently with both mineral and synthetic oils and greases. The design minimizes friction torque by approximately 80% and reduces specific heat generation by 50%, which in turn lowers power loss and operational costs while increasing seal service life, thereby reducing costly downtime.

The shaft seal is pressure stable up to 0.5 bar and supports bidirectional rotating shafts operating at velocities up to 40 m/s. It meets ISO h11 shaft tolerance and H8 housing bore tolerance standards, ensuring precise fit and reliable sealing performance.

Manufactured in the Czech Republic, this seal is crafted to meet high-quality control standards and industrial reliability. Constructed with 72 Nitrile Butadiene Rubber 902 for exceptional durability. Precision dimensions: 25 mm ID, 36 mm OD, 7 mm thickness.

Compatible with mineral and synthetic oils and greases. Reduces friction and heat, extending operational life. Suitable for aerospace, automotive, power transmission, and industrial machinery. Pressure stable to 0.5 bar, supports shafts up to 40 m/s.

Replacement for R21 and some R4 Seals. Meets ISO h11 shaft and H8 housing bore tolerances. Explore more sealing solutions and industrial components within EnvMart categories for mechanical machinery and power transmission.
