A pivot assembly bearing having a bearing inner ring, a shaft, a bearing outer ring, a housing, and an UV curable anaerobic adhesive fixing the bearing inner ring to the shaft, and the bearing outer ring to the housing, wherein the adhesive includes 15 to 25% of urethane acrylate, 45 to 55% of acrylic acid diester, less than 3% of acrylic acid monomer, 15 to 30% of hydroxyalkylmethacrylate, less than 3% of anaerobic catalyst, and less than 3% of photopolymerization initiating agent, and in addition, a coloring agent, if necessary. The pivot assembly bearing reduces outgas, shortens adhesive curing time, and no tack at the adhesive surface is obtained. |
