The encoder seal corresponds to the speed sensor in the wheel bearing and is assembled between the hub and the knuckle to transmit the rotation and steering of the hub. In addition, it is mounted on the car wheel drive bearing and detects the change of the output signal when the rotation and stop between each wheel is detected. It is an important part to drive the ABS and it operates according to the magnetic N / S output signal. , A high-power encoder seal with a MAG flux density of 1.3mT or more, a single pitch error of within ± 1.8%, and a total pitch error of 3.0% or less at an air gap of 3.0 mm is required. In this paper, the quality and test evaluation of encoder seal using ferrite compounding and spinning process optimization method were performed. First, the error measurement of the encoder seal was verified by comparing the 3D modeling with the SCAN DATA. The mechanical properties of the rubber compound were evaluated and it was verified that the corrosion and distortion of the seal occurred. Evaluation was performed to confirm the physical properties.
