Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 30 mm ID 42 mm OD 7 mm 40413409

Freudenberg Sealing Technologies Simrit 40413409 is a rotary shaft seal manufactured from 72 Nitrile Butadiene Rubber (NBR) 902, measuring 30 mm inside diameter, 42 mm outside diameter, and 7 mm thickness. The seal integrates a spring-loaded lip design optimized for use with mineral and synthetic oils and greases, delivering excellent wear resistance and operational reliability.

This high-performance Simmering radial seal offers reduced frictional torque by approximately 80% and lowers specific heat generation by up to 50%. Such enhancements contribute to extended seal life and reduced operational power losses, making it ideal for a wide range of heavy-duty industrial applications, including aerospace, railway, power transmission, automotive, machine tools, fluid handling, and energy generation.

The seal is pressure stable up to 0.5 bar and designed for bidirectional rotating shafts with velocities up to 40 meters per second. It meets strict dimensional tolerances with shaft tolerance ISO h11 and housing bore tolerance H8 for precise fitting and performance reliability.

It serves as a suitable replacement for various standard rotary shaft seals such as R21 and, in some cases, R4 seals. The robust elastomer outer casing combined with the spring-loaded sealing lip ensures durability and excellent sealing performance even under challenging operating conditions.

Constructed from high-quality 72 Nitrile Butadiene Rubber 902. Spring-loaded sealing lip ensures the reliability of rotary shaft sealing. Compatible with mineral and synthetic oils and greases. Pressure stable up to 0.5 bar for diverse industrial requirements.

Bidirectional shaft compatibility up to 40 m/s velocity. Reduces frictional torque and heat generation effectively. Dimensions: 30 mm ID, 42 mm OD, 7 mm thickness. Manufactured in Czech Republic adhering to stringent quality standards.

This product is essential for industrial, automotive, manufacturing, and power transmission applications where robust and reliable shaft sealing is paramount. Freudenberg Sealing Technologies Simrit products offer advanced sealing solutions to minimize maintenance and increase equipment uptime.
