Metric thin-wall bearings are developed for bearing space constraints. As the name suggests, the wall thickness of the inner and outer rings of the bearing is thinner. Although the design affects a certain load capacity, the bearing can still accommodate relatively light radial thrust loads or axial and radial combined loads. According to different sizes, they can be divided into 67/68/69 series bearings. Due to the smaller space required, they are widely used in the working environment of cloud head, UAV and other lightweight requirements.
