<P>PROBLEM TO BE SOLVED: To provide a vibration control bearing for an ABS (anti-lock system) pump capable of maintaining the elasticity of a resin ring over a long period of time even in existence of a PGA (polyakylene glycol) type oil such as a brake liquid. <P>SOLUTION: A circumferential groove 1a provided on an outer peripheral face 1x of an outer ring 1 of the vibration control bearing is formed, and the resin rings 5, 5 are respectively formed by injection molding using a polyether ether ketone resin so as to cover the circumferential groove 1a. By this constitution, the resin ring 5 can maintain sufficient elasticity over a long period of time without being influenced by swelling or the like even in the brake liquid. Accordingly, the vibration control bearing for the ABS pump of this invention can have a long service life maintaining vibration control effect for a long period even in the existence of the PGA type oil. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
