Hub unit bearings with an ABS sensor

摘要

In this paper, we introduce NSK's wheel hub unit bearings that contain either a built-in speed sensor or a separate sensor rotor. Our bearings can be roughly categorized into four designs: (1) Bearings with a built-in annular passive sensor, (2) Bearings with a sensor between each row, (3) Bearings with a multi-pole magnetic encoder seal, and (4) Bearing with an end-cap sensor. We will propose an appropriate design for each application based on four kinds of sensor-integrated bearings.
