Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal, 25 mm ID, 47 mm OD, 10 40412530

Freudenberg Sealing Technologies Simrit 40412530 rotary shaft seal is made from 72 nitrile butadiene rubber 902, offering high performance in sealing rotating shafts with dimensions of 25 mm inside diameter, 47 mm outside diameter, and 10 mm thickness. This seal is specifically engineered to deliver exceptional wear resistance and operational life, supporting various industrial uses such as aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, and power generation.

The seal features an elastomer outer casing with NBR 902 nitrile rubber and a spring-loaded sealing lip, enabling it to work efficiently with both mineral and synthetic oils and greases. It complies with shaft tolerance ISO h11 and housing bore tolerance H8 to ensure precision and reliability in installation and operation. The design minimizes friction torque by 80% and reduces specific heat generation by 50%, resulting in lower power loss and longer service intervals, which helps reduce downtime and maintenance costs.

This rotary shaft seal maintains pressure stability up to 0.5 bar and supports bidirectional rotating shafts with speeds up to 40 meters per second. It serves as a suitable replacement for R21 and in some cases R4 seals as per manufacturers’ data sheets, broadly applicable in axles, power tools, industrial gearboxes, motors, and pumps.

Manufactured in Czech Republic, this seal matches high standards for quality and industrial performance. Its robust material profile and engineering enhance durability against mechanical wear and heat generation, making it indispensable in demanding industrial environments.

Constructed from high-quality 72 nitrile butadiene rubber 902. Ensures pressure stability and supports high-speed bidirectional rotation. Reduces friction torque and heat generation significantly. Compatible with a wide range of oils and greases.

Meets stringent industrial shaft and bore tolerance standards. Applicable in aerospace, automotive, manufacturing, and energy industries. Manufactured in Czech Republic, ensuring consistent quality.
