Deep groove ball bearings are non-separable bearings, with simple structure, low friction factor and high limiting speed. They are the most widely used, mainly support radial load as well as a certain amount of axial load. When the radial clearance increases, they have the function of supporting axial load as angular contact ball bearings.Deep groove ball bearings have a variety of structure. In addition to general open type, WZZZ also provide bearings with bearing shield on one side, bearing shield on double sides, sealed on one side and sealed on double sides. All sealed bearings are filled with lubrication grease before leaving the factory and users need not clean and add grease. We also provide deep groove ball bearings with snap ring groove in outer ring. The structure can use snap rings to fix bearing in the bearing box. This is an advantage in application with confined assembly space.
