Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 30 mm ID, 47 mm OD, 10 40412526

Freudenberg Sealing Technologies Simrit model 40412526 rotary shaft seal features 72 Nitrile Butadiene Rubber 902 elastomer providing exceptional wear resistance and enhanced sealing for rotary shafts. With a 30 mm inside diameter, 47 mm outside diameter, and 10 mm thickness, this seal is designed for demanding industrial environments.

The seal's spring-loaded sealing lip ensures efficient sealing performance with mineral and synthetic oils and greases commonly used in automotive, aerospace, railway, power transmission, and fluid handling systems. Its design reduces friction and heat generation, contributing to lower power loss and extended seal life, ultimately reducing costly downtime and maintenance.

The seal offers up to 80% less friction torque and 50% less heat generation compared to conventional seals, improving machine efficiency. It is pressure stable up to 0.5 bar and supports bidirectional shaft rotation at speeds up to 40 m/s. The product serves as a suitable replacement for R21 and R4 seals in various machinery including industrial gearboxes, motors, pumps, and power tools.
