Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal, 45 mm ID, 60 mm OD, 7 mm 40411326

Freudenberg Sealing Technologies Simrit model 40411326 is a high-performance rotary shaft seal made from 72 Nitrile Butadiene Rubber 902, designed to deliver exceptional wear resistance in industrial, automotive, power transmission, and manufacturing applications. It features a 45 mm inside diameter, 60 mm outside diameter, and 7 mm thickness, with a spring-loaded sealing lip and elastomer outer casing that withstands mineral and synthetic oils and greases effectively.

The seal offers significant reductions in friction torque, heat generation, and wear compared to conventional seals, resulting in lower power loss and extended service life. It is pressure stable up to 0.5 bar and suited for bidirectional rotating shafts operating at velocities up to 40 meters per second. This product serves as a suitable replacement for R21 and occasionally R4 seals, supporting varied industrial uses including aerospace, railway, machine tools, fluid handling, energy production, and automotive sectors.

Manufactured in the Czech Republic, this seal adheres to ISO h11 shaft tolerance and H8 bore housing tolerance standards for precision fitment. This rotary shaft seal provides exceptional wear resistance and durability. Constructed with a spring-loaded sealing lip and NBR 902 nitrile rubber elastomer casing.

Compatible with mineral and synthetic oils and greases for versatile industrial use. Reduces friction, heat generation, and wear to improve machine efficiency and lower running costs. Suitable for bidirectional rotating shafts with speeds up to 40 m/s and pressure stability up to 0.5 bar.

Ideal replacement for R21 and sometimes R4 seals in applications such as axles, gearboxes, motors, and pumps. Manufactured in Czech Republic ensuring stringent quality standards.

This shaft seal is essential for industries requiring reliable sealing solutions in harsh environments, including construction machinery, power tools, industrial gearboxes, water pumps, and energy generation equipment. EnvMart offers this product as part of its comprehensive catalog of mechanical Seals and related components for professional industrial use.
