Review NATIONAL SEAL/BEARING Seals Mr 1205 El Multi Purpose

The MR1205EL seals, manufactured by National Seal & Bearing, are engineered to provide exceptional performance in various industrial applications. These seals are part of National Seal & Bearing's extensive line of elastomeric seals, which are known for their durability and reliability.

The MR1205EL seals are designed with a diameter of 1.25 inches and a width of 0.5 inches. They are made from a high-quality elastomer material that offers excellent resistance to both compression and tension loads. The elastomer used in these seals is specifically formulated to provide superior resistance to abrasion, tear, and aging, making them ideal for use in harsh environments.

These seals feature a lip thickness of 0.187 inches, which provides ample sealing surface area for a wide range of applications. The lip design of the MR1205EL seals is asymmetrical, meaning that one side of the lip is thicker than the other to accommodate uneven shaft surfaces. This design feature allows the seals to effectively seal against shafts with minor misalignments or uneven surfaces.

The MR1205EL seals come with an optional spring load, which can be used to apply additional pressure to the seal face and improve sealing performance. The spring load can be adjusted to accommodate different application requirements.

National Seal & Bearing's MR1205EL seals are suitable for use in a variety of industries, including oil and gas, power generation, mining, and water treatment. They are commonly used in rotating equipment such as pumps, compressors, and electric motors, where sealing is critical for maintaining efficiency and preventing leaks.

These seals are also available in various materials and hardness levels to meet specific application requirements. For instance, they can be made from materials such as nitrile, Buna-N, EPDM, and Viton, among others. The hardness level can also be customized to suit the operating conditions of the application.

Overall, the MR1205EL seals from National Seal & Bearing are an excellent choice for industrial applications that require robust, reliable sealing solutions. Their high-quality materials, versatile design, and adjustable spring load make them a popular option for a wide range of industries and applications.
