发明名称 Magnetic encoder and wheel bearing assembly using the same
摘要 To provide a magnetic encoder in which an air gap between it and a magnetic sensor can be increased and the magnetic force generated thereby can be easily quality-controlled, and a wheel bearing assembly having the magnetic encoder, the magnetic encoder 20 includes a core metal 11 and an elastic member 14 integrated with the core metal 11 in a ring-shaped configuration. The elastic member 14 is made from an elastic material mixed with a powder of magnetic material and has a plurality of different magnetic poles alternating in a direction circumferentially thereof. The elastic member 14 also has a Shore hardness of not lower than Hs 90. A wheel bearing assembly is also provided, which makes use of the magnetic encoder 20 as a component part of a sealing unit 5.
