Freudenberg Sealing Technologies Simrit Rotary Shaft Seal 25 mm ID, 38 mm OD, 7 mm Thickness, 72 Nitrile Butadiene 40411185

Freudenberg Sealing Technologies Simrit 40411185 rotary shaft seal features a 72 Nitrile Butadiene Rubber 902 elastomer outer casing and a spring-loaded sealing lip, designed for exceptional wear resistance and performance in industrial environments.

With an inside diameter of 25 mm, outside diameter of 38 mm, and thickness of 7 mm, this seal is engineered for a variety of mechanical and fluid power applications including aerospace, railway, power transmission, automotive, machine tools, fluid handling, production line equipment, energy, and power generation.

The seal material offers high resistance to mineral and synthetic oils and greases, providing stable operation with reduced friction torque, heat generation, and wear, thereby extending equipment operating life and reducing downtime.

This product is pressure stable up to 0.5 bar and suitable for bidirectional rotating shafts reaching velocities up to 40 meters per second. It has a shaft tolerance conforming to ISO h11 and housing bore tolerance H8, contributing to precise fitment and reliable sealing.

Freudenberg Simrit 40411185 seals serve effectively as replacements for older R21 and sometimes R4 seal models, making it versatile for maintenance and retrofitting purposes. Typical applications include use on industrial gearboxes, motors, pumps, axles, and power tools.

Durable 72 Nitrile Butadiene Rubber 902 elastomer construction ensures long-lasting performance. Optimized design reduces friction torque by approximately 80% compared to standard seals. Significant reduction in heat generation by about 50% enhances efficiency.

Stable sealing under pressures up to 0.5 bar protects machinery components. Spring loaded sealing lip provides excellent wear resistance during shaft rotation. Compatible with both mineral and synthetic lubricants. ISO h11 shaft tolerance and H8 housing bore tolerance for precision fitting.

Application range includes automotive, power transmission, machine tools, and fluid handling. Enhances equipment lifespan by minimizing wear and lowering operating costs. Suitable replacement for R21 and some R4 seal types.
