Deep groove ball

6011

6011 is a deep groove ball designation documented on BearingIndex from 3 independent manufacturer publications. The published boundary dimensions are 55 × 90 × 18 mm. The designation ends in bore code 11, which resolves to a 55 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.

Bore d: 55 mm
Outside D: 90 mm
Width B: 18 mm
