super thin series deep groove ball bearing products are divided into 2 series: 618 series, 619 series. These series bearings can save space, reduce weight, significantly reduce friction, and offer good rotation accuracy. It also can effectively reduce the external dimensions of the machine and reduce production cost without affecting bearing performance and service life.
