What is the structure and classification of deep groove ball bearings?

Bearing structure
Deep groove ball bearings have a simple structure and are easier to achieve higher manufacturing accuracy than other types. Therefore, they are easy to produce in series and have lower manufacturing costs, and they are extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, and Deep groove ball bearing with large load capacity with ball gap, double row deep groove ball bearing.
Bearing type
Deep groove ball bearings are mainly used to bear radial loads, but they are also commonly used to bear combined radial and axial loads. Especially when the speed of mechanical equipment is very high and thrust bearing is not suitable, the bearing can be used to bear bidirectional pure axial load, and it does not need maintenance during operation. It is a kind of bearing with low price and wide application. The models of deep groove ball bearings are: deep groove ball bearings (60000 type); deep groove ball bearings with a stop groove on the outer ring (60000N type); deep groove ball with a dust cover on one side and a stop groove on the other side Bearing (60000-ZN type); Deep groove ball bearing with dust cover on both sides and stop groove on the outer ring (60000-2ZN type); Deep groove ball bearing with dust cover on one side (60000Z type); both sides Deep groove ball bearing with dust cover (60000-2Z type); deep groove ball bearing with sealing ring on one side (60000-LS type, 60000-RZ type); deep groove ball bearing with sealing ring on both sides (60000- 2LS type, 60000-2RZ type); flanged outer ring deep groove ball bearing (F60000 type); flanged outer ring deep groove ball bearing with dust cover on one side (F60000-Z type); with dust cover on both sides There are 11 types of deep groove ball bearings with flanged outer ring (F60000-2Z type).
According to the size of deep groove ball bearings can be divided into:
(1) Miniature bearings-bearings with a nominal outer diameter range of 26mm or less;
(2) Small bearings-bearings with a nominal outer diameter range of 28-55mm;
(3) Small and medium-sized bearings-bearings with a nominal outer diameter range of 60-115mm;
(4) Medium and large bearings-bearings with a nominal outer diameter range of 120-190mm
(5) Large bearings-bearings with a nominal outer diameter range of 200-430mm;
(6) Extra-large bearings-bearings with a nominal outer diameter range of 440mm or more.
