Deep groove ball bearings are mainly used to accommodate radial loads, but are also commonly used to accommodate radial and axial combined loads. Especially when the speed of mechanical equipment is very high and it is not suitable to use thrust bearings, the bearing can be used to bear pure axial load in both directions, and no maintenance is required during work, which is a kind of bearing with low price and wide use. Deep groove ball bearing types are: deep groove ball bearings (60000 type); Deep groove ball bearings with stop grooves on the outer ring (type 60000N); Deep groove ball bearings with shield on one side and stop groove on the outer ring on the other (type 60000-ZN); Deep groove ball bearings with shields on both sides and stop grooves on the outer ring (type 60000-2ZN); Deep groove ball bearing with shield on one side (type 60000Z); Deep groove ball bearings with shields on both sides (type 60000-2Z); Deep groove ball bearings with seals on one side (type 60000-LS, type 60000-RZ); Deep groove ball bearings with seals on both sides (type 60000-2LS, type 60000-2RZ); Deep groove ball bearings on the flange outer ring (type F60000); Deep groove ball bearings with flanged outer ring with shield on one side (type F60000-Z); There are 11 types of deep groove ball bearings (type F60000-2Z) with flanged outer ring with shields on both sides.
According to the size of deep groove ball bearings, they can be divided into:
(1) Miniature bearings ---- bearings with a nominal outer diameter size range of 26mm or less;
(2) Small bearings ---- bearings with a nominal outer diameter size range of 28-55mm;
(3) Small and medium-sized bearings---- bearings with a nominal outer diameter size range of 60-115mm;
(4) Medium and large bearings ---- bearings with a nominal outer diameter size range of 120-190mm
(5) Large bearings ---- bearings with a nominal outer diameter size range of 200-430mm;
(6) Extra large bearings ---- bearings with a nominal outer diameter size range of 440mm or more.
