Rotary Shaft Seal: What Is It, And Why Does It Matter?

Product Details: Rotary shaft seals, also known as lip seals, are designed to seal rotary elements such as shafts or rotating bores. They are used to retain lubricants and exclude contaminants like dirt, dust, and water. These seals consist of a cylindrical outer covering, a sealing lip made of elastomers like NBR, FKM, or HNBR, and a garter spring to maintain constant force on the shaft. The sealing lip has a line contact with the shaft, and the angles of this contact are designed to create a pressure distribution that enhances sealing efficiency. They are widely used in applications such as hydraulic

pumps, power steering, axle seals, and valve stem seals[1][2][3].
