High-Performance 620zz Ball Bearings - Set of 10】 Outer diameter: 6.0mm Inner diameter: 2.0mm Thickness: 2.5mm This is a high-performance product with the lowest rolling resistance among the currently available 620 bearings. The outer ring is as thick as the old 620, making it resistant to chassis twisting and reducing loss. Since the bearings have not been degreased, please perform basic maintenance such as cleaning with a cleaner and lubrication before use.
