Product Description
Freudenberg Sealing Technologies Simrit 40411213 rotary shaft seal is engineered for high performance in industrial, automotive, aerospace, and power transmission applications. It features a durable 72 Nitrile Butadiene Rubber 902 elastomer outer casing with a spring-loaded sealing lip that provides excellent wear resistance and heat management, lowering friction and power loss. The seal dimensions - 28 mm inside diameter, 42.5 mm outside diameter, and 8 mm thickness - offer precise fitment suitable for rotary shafts.
These shaft seals are pressure stable up to 0.5 bar and perform reliably up to 40 meters per second in bidirectional rotation, suitable for motors, pumps, gearboxes, and power tools. The material compatibility with mineral and synthetic oils and greases extends the seal's versatility across multiple industries including aerospace, railway, energy, and manufacturing.
Simrit seals considerably reduce maintenance downtime by enhancing seal durability and minimizing wear and heat generation. With strict shaft tolerance conformity to ISO h11 and housing bore tolerance H890, they ensure reliable sealing and reduced friction torque.
The seal offers 80% less friction torque compared to traditional designs. It generates 50% less specific heat, contributing to energy efficiency. Wear reduction enhances equipment lifespan and reduces maintenance intervals.
Material and design provide robustness against diverse industrial conditions. Ideal for replacing R21 and in some cases R4 seals, following manufacturers’ data sheets.
This product is manufactured in the Czech Republic with high quality standards. Ideal for industrial, laboratory, construction, automotive, and power transmission sectors requiring reliable rotary shaft sealing solutions.
