This type of bearing has small friction coefficient, high rotational speed, simple structure, low manufacturing cost, and relatively easy to achieve high precision. It mainly bears radial load, and can also bear a certain amount of axial load. Compared with other types of deep groove ball bearings of the same size and size, this type of bearing has a small friction coefficient and a high limit speed. However, it is not shock resistant and not suitable for heavy loads.
There’s three series about the thin section Ball Bearing 6700 series, 6800 series and 6900 series.
