Abstract
A bearing assembly is proposed which includes a rotational speed detector including a sensor and a sensor holder made of steel. The sensor is adapted to be snap-fitted in the sensor holder. The sensor holder is subjected to cationic electrocoating to improve its corrosion resistance, thereby preventing the sensor from separating from the sensor holder after long use of the bearing assembly. This improves the reliability of the entire bearing assembly.
