6907

6907 is a deep groove ball designation documented on BearingIndex from 3 independent manufacturer publications. The published boundary dimensions are 35 × 55 × 10 mm. The designation ends in bore code 07, which resolves to a 35 mm bore under ISO 15 and matches what the manufacturers published. The publishing works are in Zhejiang province, China. Every value below comes from that manufacturer’s own published material, with the date it was recorded.
