Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 20 mm ID, 32 mm OD, 7 mm 40413835

Freudenberg Sealing Technologies Simrit 40413835 rotary shaft seal is engineered with 72 Nitrile Butadiene Rubber 902 elastomer providing outstanding wear resistance and sealing performance. Measuring 20 mm inside diameter, 32 mm outside diameter, and 7 mm thickness, this seal offers reliable sealing for rotary shafts in a variety of industrial sectors including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production line systems, energy, and power generation.

The seal features a spring-loaded sealing lip that tolerates mineral and synthetic oils and greases, enhancing durability under demanding operating conditions. It is pressure stable up to 0.5 bar and supports bidirectional shaft rotation at speeds up to 40 meters per second. The product is designed in accordance with ISO h11 shaft tolerance and H8 housing bore tolerance ensuring a precise and secure fit.

This seal offers up to 80% less friction torque and 50% less specific heat generation compared to conventional seals, effectively reducing power loss, operational wear, and maintenance downtime. It is a recommended replacement for R21 seals and, in some cases, R4 seals, providing a versatile sealing solution across applications.

Typical applications include axles, power tools, industrial gearboxes, motors, and pumps. Originating from the Czech Republic, this seal meets high industrial standards and supports efforts to improve equipment longevity and efficiency.

Constructed from wear-resistant 72 Nitrile Butadiene Rubber 902 elastomer. Spring-loaded sealing lip designed for mineral and synthetic lubricant compatibility. Maintains pressure stability up to 0.5 bar and supports bidirectional shaft speed up to 40 m/s.
