The Fruedenberg-NOK MileMaker wheel sealsare made of an advanced elastomer that withstands higher operating temperatures of up to 350 degrees F and are compatible with mineral oil, synthetic oil and grease lubricants. The MileMaker seal incorporates patented dirt-exclusion fins that assist with keeping contamination away from the seal. The lubed rubber outer diameter and inner diameter design eases installation force, which results in less heat generation and increased seal life, and seals any minor hubs or spindle imperfections. The seal design has low internal torque aided by an internal lubricant, which translates to lower internal heat generation, excellent wear resistance and improved fuel economy.
