Abstract: PURPOSE: A bearing seal for a vehicle and a manufacturing method thereof are provided to add a nano particle dispersed by a wet dispersion method to an acrylonitrile- butadiene rubber resin for improving abrasion resistance, and to secure low torque and high airtight properties. CONSTITUTION: A manufacturing method of a bearing seal for a vehicle comprises the following steps: producing a bulk type nano diamond(120); forming a first additive solution by mixing the bulk type nano diamond with a dioctyl-phthalate solution(100); adding the first additive solution to ethanol, and performing a wet milling process to pulverize the nano diamond into 10~200 nano meters; forming a second additive solution with the uniformly dispersed nano diamonds; forming a third additive solution by drying the second additive solution to evaporate the ethanol; and manufacturing the bearing seal by mixing 2.1~3wt% of third additive solution, 35~33wt% of rubber resin, and 42~62.0wt% of additives including carbon black.
