Deep groove ball bearings are designed as non-separable bearings with the characteristics of simply designed structures; low friction coefficient and high limit rotational speed. They can mainly carry radial load and certain axial load. When the radial internal clearance increases, the bearings have the funtions of angular contact ball bearings that a larger axial load can also be carried.
Deep groove ball bearigns are comprose various structures, bebsides open bearings; we can also see single shielded/sealed bearings, double shielded/sealed bearings. All bearings are prefilled with lubricating grease; the users can direct start it without cleaning and lubricating it first. In addition, deep groove ball bearings with snap ring groove on outer rings are strongly recommonded to you, as this kind of bearing can use snap rings to easily fix the bearings in the bearing box. So when the mounting position is restrained, take deep groove ball bearings with snap ring groove on outer rings as priority. Mostly, deep groove ball bearigns use ribbon cage made of pressed steel sheet, or solid cage. See Table 1 for the permissible tilting angle between the rinner ring and outer ring of this kind of bearings.
