Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber 902 Rotary Shaft Seal 48 mm ID 65 mm OD 10 mm 40411337

Freudenberg Sealing Technologies Simrit 40411337 rotary shaft seal, constructed with high-quality 72 Nitrile Butadiene Rubber 902 elastomer, features a 48 mm inside diameter, 65 mm outside diameter, and 10 mm thickness. This premium seal is designed for demanding industrial applications requiring exceptional wear resistance, durability, and sealing efficiency.

The NBR 902 nitrile rubber outer casing combined with a spring-loaded sealing lip provides excellent resistance to mineral and synthetic oils and greases, making it highly versatile for various fluids. The seal effectively minimizes friction torque by approximately 80% and reduces specific heat generation by 50%, contributing to lower power loss and improved operational efficiency.

Stability under pressure up to 0.5 bar and suitability for bidirectional rotating shafts at speeds up to 40 m/s make this seal reliable for diverse mechanical applications. It complies with shaft tolerance ISO h11 and housing bore tolerance H8, ensuring a precise fit and reliable sealing performance.

This sealing solution is widely used in aerospace, railway, automotive, power transmission, machine tools, fluid handling, production lines, energy, and power generation industries. It provides significant improvements in wear and heat resistance, reducing maintenance costs and costly downtime caused by seal repairs.

The seal serves as a recommended replacement for R21 and, in some cases, R4 seals, following manufacturers’ datasheets. Made in the Czech Republic, this product embodies strict quality and performance standards.
