Product Description
Freudenberg Sealing Technologies Simrit model 40412558 is a high-quality rotary shaft seal made from 72 Nitrile Butadiene Rubber 902. It features an inside diameter of 52 mm, an outside diameter of 72 mm, and a thickness of 8 mm. This seal is engineered to deliver outstanding wear resistance and reliability in demanding industrial environments.
The spring-loaded sealing lip allows for effective sealing with both mineral and synthetic oils and greases. This design reduces friction torque by approximately 80%, lessens specific heat generation by 50%, and minimizes wear, thereby reducing power loss and lowering operational costs.
The seal maintains pressure stability up to 0.5 bar and is suitable for bidirectional rotating shafts with velocities up to 40 m/s. It is ideal for a broad range of applications including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production lines, energy production, and power generation industries.
It provides a reliable replacement option for R21 and in some cases R4 seals, compatible with specified shaft and housing tolerances (shaft tolerance ISO h11 and housing bore tolerance H8). Manufactured in the Czech Republic, this IMS seal ensures consistent quality and performance in mechanical systems.
