Description

The National 10X20X7 is an oil and grease seal designed to contain lubrication and prevent contaminants from entering rotating machinery. Its size is determined by the shaft diameter, housing bore diameter, and seal width, ensuring a proper interference fit for the operating conditions. This seal is suitable for high-speed rotation when designed and applied correctly, considering material type, lip design, and shaft surface finish.
