Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 72 Nitrile Butadiene Rubber 902, 45 mm ID, 65 mm OD, 10 40412528

Freudenberg Sealing Technologies Simrit 40412528 is a high-performance rotary shaft seal manufactured using 72 Nitrile Butadiene Rubber 902 elastomer, designed to provide exceptional wear resistance and sealing effectiveness for demanding industrial applications. This seal features a 45 mm inside diameter, 65 mm outside diameter, and 10 mm thickness, optimized for rotary shafts.

The elastomer outer casing made from NBR 902 nitrile rubber combined with a spring-loaded sealing lip allows it to perform well with both mineral and synthetic oils as well as greases. This design reduces friction torque by approximately 80% and specific heat generation by 50%, resulting in a longer operational life and reduced downtime.

Pressure stability of up to 0.5 bar and capability for bidirectional rotation at velocities up to 40 meters per second make this seal suitable for a broad range of heavy-duty industrial environments. It serves as a reliable replacement for R21 and sometimes R4 seals, applicable in axles, power tools, industrial gearboxes, motors, and pumps.

Common industrial uses include aerospace, railway, power transmission, automotive manufacturing, machine tooling, fluid handling systems, production lines, energy, and power generation sectors. Its robust construction ensures reduced wear and extended seal life, supporting maintenance cost savings and operational efficiency.

This seal is designed for rotary shafts to deliver excellent oil sealing performance. Constructed with 72 Nitrile Butadiene Rubber 902 elastomer for high wear resistance. Suitable for use with mineral and synthetic oils and various greases.

Features a spring-loaded sealing lip to maintain effective sealing under pressure. Pressure stable up to 0.5 bar and suitable for bidirectional rotating shafts up to 40 m/s velocity. Significant reduction in friction torque and heat generation helps lower power loss and running costs.

Applications include aerospace, railway, power transmission, automotive, machine tools, fluid handling, energy, and power generation industries. Manufactured in Czech Republic ensuring high quality.
