Freudenberg Sealing Technologies Simrit 72 Nitrile Butadiene Rubber Rotary Shaft Seal 35 mm ID, 52 mm OD, 7 mm 40413202

Freudenberg Sealing Technologies Simrit 40413202 is a high performance rotary shaft seal made of 72 Nitrile Butadiene Rubber 902, designed for industrial and mechanical applications requiring excellent wear resistance and sealing efficiency. The seal has a 35 mm inside diameter, 52 mm outside diameter, and a thickness of 7 mm, suitable for accommodating rotating shafts with ISO h11 shaft tolerance and H8 housing bore tolerance.

This seal incorporates a spring-loaded sealing lip that minimizes friction torque by 80% and reduces specific heat generation by 50%, which helps reduce power loss and extends the working life of equipment by preventing premature seal failures. It is pressure stable up to 0.5 bar and can operate on bidirectional rotating shafts at velocities up to 40 meters per second.

The seal is a recommended replacement for R21 and some instances of R4 seals and is widely used in axles, power tools, industrial gearboxes, motors, and pumps. Its design ensures reduced wear and friction, leading to lower operational costs and minimized downtime for maintenance.

Constructed from 72 Nitrile Butadiene Rubber 902 for chemical and wear resistance. Spring-loaded sealing lip reduces friction torque and heat generation. Pressure stable up to 0.5 bar for reliable sealing performance. Supports bidirectional rotating shafts up to 40 m/s velocity.

Manufactured under ISO h11 and H8 tolerances for precise fit. Suitable for use with mineral and synthetic oils and greases. Applications include automotive, aerospace, power transmission, and fluid handling industries. Origin: Czech Republic.
