Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 40 mm ID 52 mm OD 7 mm 40413760

Freudenberg Sealing Technologies Simrit 40413760 rotary shaft seal features a 40 mm inside diameter, 52 mm outside diameter, and 7 mm thickness, constructed with 72 Nitrile Butadiene Rubber 902 elastomer for high resistance to mineral and synthetic oils and greases.

This high-performance shaft seal includes a spring-loaded sealing lip that significantly reduces friction torque, wear, and heat buildup, delivering reliable sealing performance for rotating shafts.

Designed to meet ISO shaft tolerance h11 and housing bore tolerance H8, it provides a snug fit, ensuring pressure stability up to 0.5 bar and suitability for bidirectional shaft rotation up to speeds of 40 m/s.

Commonly used in industrial sectors such as aerospace, railway, automotive, power transmission, energy generation, and production line machinery, this seal helps reduce power loss and operational costs by extending seal life and improving equipment uptime.

Exceptional wear resistance with spring-loaded lip design. Compatible with mineral and synthetic oils and greases. ISO h11 shaft tolerance and H8 housing tolerance ensure precise fitting. Reduces friction torque by approximately 80% and heat generation by 50% compared to traditional seals.

Pressure stable up to 0.5 bar and supports speeds up to 40 m/s. Applicable for diverse industrial uses including motors, pumps, gearboxes, and power tools. Manufactured in Czech Republic ensuring quality and reliability.

This seal is an essential component for maintaining efficient and reliable rotating shaft operations across industrial, manufacturing, and fluid power applications. Browse more in the mechanical seals category at EnvMart for compatible Sealing solutions.
