Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 32 mm ID, 47 mm OD, 7 mm 40413726

Freudenberg Sealing Technologies Simrit 40413726 is a premium rotary shaft seal manufactured from 72 Nitrile Butadiene Rubber 902 designed for demanding industrial environments. The seal features a 32 mm inside diameter, 47 mm outside diameter, and a thickness of 7 mm, making it suitable for a wide range of mechanical and fluid power applications.

The elastomer outer casing of NBR 902 nitrile rubber combined with a spring-loaded sealing lip offers exceptional wear resistance and performance. This seal is compatible with both mineral and synthetic oils and greases, making it versatile for various lubrication requirements.

Key benefits include significantly reduced friction torque (80% less) and specific heat generation (50% less), which translates to lower power loss and improved energy efficiency. It is pressure stable up to 0.5 bar and supports bidirectional rotating shafts at velocities up to 40 m/s, ensuring reliable sealing performance under challenging operating conditions.

Applications for this seal span a broad industrial spectrum including aerospace, railway systems, power transmission, automotive components, machine tools, fluid handling systems, production lines, energy generation, and more. This durability helps minimize equipment downtime and maintenance costs.

Specifically engineered as a replacement for R21 and in some cases R4 seals, this product suits axles, power tools, industrial gearboxes, motors, and pumps. The shaft tolerance meets ISO h11 with housing bore tolerance at H8, ensuring precision fit and sealing efficacy.

This elastomer seal is manufactured in the Czech Republic maintaining high quality standards. It offers excellent resistance to wear and friction, extending the operational life of machinery. Designed for use with various lubricants including mineral and synthetic oils and greases.

Stable under pressure and suitable for high-speed bidirectional shafts. Compatible with multiple industrial applications demanding reliable sealing solutions. Helps reduce energy loss and maintenance interventions in rotating equipment.
