Deep Groove Ball Bearing, formerly known as single-row centripetal ball bearing, is the most widely used rolling bearing. It is characterized by small frictional resistance and high speed, which can be used to bear the combined load of radial load or radial direction and axial load, and also can be used to bear the axial load.
The basic type deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. .Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open type means without seal, seal type deep groove ball bearing also have dust seal and oil seal. The dustproof sealing material is sheet metal stamping, only simple to prevent the dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease out of the bearing.
Deep groove ball bearing type:
deep groove ball bearing (60000 type);
Deep groove ball bearing with stop groove in outer ring (60000N type);
Deep groove ball bearing with a dustproof cover and a stop groove on the other side.(60000-ZN type)
Deep groove ball bearing double cover with dustproof cover and with stop groove in outer ring (60,000-2zn type);
Deep groove ball bearing with dust cover (60000Z);
Deep groove ball bearing with dust cover on both sides (60,000-2z);
Deep groove ball bearing with seal (60,000-ls type, 60,000-rz type);
Deep groove ball bearing with seals on both sides (60,000-2ls, 60000-2rz);
Deep groove ball bearing with flange (F60000 type);
Deep groove ball bearing with flange andone side dust cover(F60000-Z type).
Deep groove ball bearing with flange and both sides dust cover.(F60000-2Z).
