Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal, 45 mm ID, 65 mm OD, 8 mm 40413794

Freudenberg Sealing Technologies Simrit 40413794 rotary shaft seal is manufactured using 72 nitrile butadiene rubber (NBR 902), providing high performance and wear resistance for industrial applications. It features a 45 mm inside diameter, 65 mm outside diameter, and an 8 mm thickness, optimized for rotary shaft sealing.

This seal includes a spring-loaded sealing lip, which enables excellent sealing against mineral and synthetic oils and greases. The quality manufacturing process in the Czech Republic ensures consistent performance, longevity, and reduced maintenance requirements.

The seal is engineered to reduce friction torque by approximately 80% and specific heat generation by 50%, which contributes to lower power consumption and extended service life. It is pressure stable up to 0.5 bar, suitable for bidirectional rotating shafts up to velocities of 40 m/s.

Applications span a broad range of industrial environments including aerospace, railway, power transmission systems, automotive components, machine tools, fluid handling equipment, production line machinery, energy, and power generation.

The product's design allows replacement compatibility with R21 and occasionally R4 Seals, enhancing flexibility for maintenance and repair operations. The seal's NBR elastomer outer casing offers durability and resistance to wear.

Spring-loaded sealing lip ensures effective sealing and adaptability. Reduced friction and heat contribute to machine efficiency and lowered operating costs. Robust construction suitable for harsh industrial operating conditions.

Prolonged working life minimizing downtime and repair frequency.
