Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 20 mm ID, 42 mm OD, 7 mm 40413328

Freudenberg Sealing Technologies Simrit 40413328 is a high performance rotary shaft seal manufactured from 72 Nitrile Butadiene Rubber 902. This seal features a 20 mm inside diameter, 42 mm outside diameter, and a thickness of 7 mm, designed to deliver exceptional wear resistance and longevity in demanding industrial environments.

Equipped with a spring loaded sealing lip, this rotary shaft seal offers compatibility with both mineral and synthetic oils and greases, providing reliable sealing performance for rotating shafts. It is pressure stable up to 0.5 bar and suitable for bidirectional rotating shafts with velocities reaching 40 meters per second.

The seal’s elastomer outer casing ensures reduced friction torque by 80%, decreases specific heat generation by 50%, and limits wear, contributing significantly to reduced downtime and operational costs in applications like aerospace, railway, automotive, fluid handling, power transmission, and manufacturing machinery.

The product is suitable as a replacement for R21 and, in some cases, R4 seals, with shaft tolerance in accordance with ISO h11 and housing bore tolerance as per H8 standards. Its robust design ensures compatibility with axles, industrial gearboxes, motors, and pumps.
