Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal, 50 mm ID, 68 mm OD, 10 40411343

Freudenberg Sealing Technologies Simrit 40411343 rotary shaft seal is constructed with premium 72 Nitrile Butadiene Rubber 902 elastomer, engineered to provide exceptional sealing performance for shafts with 50 mm inside diameter, 68 mm outside diameter, and 10 mm thickness. This high-quality seal delivers outstanding wear resistance and reduces power loss due to minimized friction and heat generation, making it suitable for demanding industrial environments.

The rotary shaft seal incorporates a spring-loaded sealing lip that ensures reliable sealing with mineral and synthetic oils and greases. It maintains pressure stability up to 0.5 bar and supports bidirectional rotating shafts at velocities up to 40 m/s, enhancing operational efficiency and extending equipment lifetime.

Applications range across aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy, and power generation industries. The seal offers a suitable replacement for R21 and, in some cases, R4 Seals, providing versatility across various equipment.

Key benefits include significant reductions in friction torque by 80% and specific heat generation by 50%, which translate to improved energy efficiency and maintenance savings. The seal meets ISO shaft tolerance h11 and housing bore tolerance H8, ensuring precision fitment and dependable performance.

Manufactured with durable 72 Nitrile Butadiene Rubber 902 providing excellent wear resistance. Suitable for rotational shafts with a 50 mm internal diameter and 68 mm external diameter. 10 mm thickness ensures robust sealing with minimized leakage.
